Procedure: A stirred mixture of 1.83 g. (0.01 mole) of 2-phenylethenesulfonamide, 3.45 g. (0.025 mole) of potassium carbonate and 4.0 g. (0.015 mole) of 4-(3-phenylpropyl)piperidinocarbonyl chloride, in 75 ml. of chloroform is heated under reflux for 22 hours. The solvent is then removed by evaporation in vacuo, and to the residue is added 75 ml of 0.5N sodium hydroxide and 35 ml. of ether. The mixture is stirred for 1 hour, and then the solid which remains undissolved is removed by filtration. This affords 1.84 g. (ca. 41% yield) of the title compound as a mixture of its sodium and potassium salts. A stirred mixture of 1.83 g under reflux for 22 hours The solvent is then removed by evaporation in vacuo to the residue is added 75 ml of 0.5N sodium hydroxide and 35 ml the solid which remains undissolved is removed by filtration

Procedure: To a solution of 3.5 g. of DL-alanine methyl ester hydrochloride in 20 ml. of N,N-dimethylformamide is added 1.05 g. of a 56.6% suspension of sodium hydride in mineral oil. The mixture is stirred at ambient temperature for 15 minutes, and then 3.8 g. of N-(N,N-diphenylcarbamoyl)-2-phenylethenesulfonamide is added. The whole reaction mixture is then maintained at ca. 90° C. for 40 minutes. After being allowed to cool to room temperature, it is diluted with an excess of ether and then it is extracted with water. Acidification of the water extract with dilute hydrochloric acid causes precipitation of the crude product, which is then filtered off. The ether phase is washed with dilute hydrochloric acid, which causes a further crop of product to precipitate. It is filtered off and the two crops of product are combined. This yields 1.55 g. of material having a melting point of 135°-139° C. The crude product is recrystallized from a mixture of acetone and hexane, giving 0.70 g. of N-[N-1-methoxycarbonylethyl)carbamoyl]-2-phenylethenesulfonamide, m.p. 138°-140° C. The whole reaction mixture is then maintained at ca. 90° C. for 40 minutes to cool to room temperature it is extracted with water Acidification of the water extract with dilute hydrochloric acid precipitation of the crude product, which is then filtered off The ether phase is washed with dilute hydrochloric acid, which to precipitate It is filtered off The crude product is recrystallized from a mixture of acetone and hexane giving 0.70 g

Procedure: To a solution of 1.8 g. of 2-phenylethenesulfonamide and 4.8 g. of 1,1-diphenyl-3-(bicyclo[2.2.1]hept-2-en-5-ylmethyl)urea in 20 ml. of N,N-dimethylformamide, is added, with stirring 0.64 g. of a 56.6% dispersion of sodium hydride in mineral oil. The mixture is stirred at ambient temperature overnight, during which time a heavy precipitate forms. To the reaction mixture is then added 200 ml. of ether. After stirring for 15 minutes, the precipitate is filtered off. It is dissolved in 50 ml. of water, and then the crude product is precipitated by acidification usng concentrated hydrochloric acid. It is filtered off and recrystallized from aqueous acetone. The yield is 1.9 g. (56%) of a solid, m.p. 161°-163.5° C. The mixture is stirred at ambient temperature overnight, during which time a heavy precipitate forms To the reaction mixture is then added 200 ml After stirring for 15 minutes the precipitate is filtered off It is dissolved in 50 ml of water, and then the crude product is precipitated by acidification usng concentrated hydrochloric acid It is filtered off recrystallized from aqueous acetone

Procedure: Sodium hydride (60%) (480 mg) was added to a solution of 1.00 g of 2-phenylethenesulfonamide in 10 ml of dimethylformamide with ice cooling followed by stirring at room temperature for 15 minutes. To this reaction solution was added 1.91 g of 4,6-dichloro-5-(2-methoxyphenoxy)-2-(2-pyrimidinyl)-pyrimidine with stirring. The reaction mixture was stirred at room temperature for 2.5 hours and poured into a mixture of 1N hydrochloric acid and ice. The resulting crystals were collected by filtration and pulverized in hot ethanol. After allowing to cool, the crystals were collected by filtration to give 1.91 g of N-[6-chloro-5-(2-methoxyphenoxy)-2-(2-pyrimidinyl)-4-pyrimidinyl]-2-phenylethenesulfonamide. with stirring The reaction mixture was stirred at room temperature for 2.5 hours The resulting crystals were collected by filtration to cool the crystals were collected by filtration
