Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 2.11 g quantity of 4-(3-ethoxy-2-hydroxypropoxy)aniline and 1.53 g of triethylamine were dissolved in 50 ml of dichloromethane. To the solution was added 1.71 g of 3-(methylsulfonyl)propionyl chloride with ice cooling. The same subsequent procedure as in Example 2 was repeated and recrystallization from benzene was performed, giving 3.25 g of N-[4-(3-ethoxy-2-hydroxypropoxy)phenyl]-3-(methylsulfonyl)propionamide in a yield of 94.2 %. M.p. 111° to 112° C. recrystallization from benzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dissolved in 4 ml of dimethylformamide were 1.46 g of triethylamine and 1.52 g of 4-(3-ethoxy-2-hydroxypropoxy)aniline. A 1.10 g quantity of 3-methylmercaptopropionyl chloride was added to the solution with ice-cooling. The mixture was stirred at room temperature for 12 hours and the reaction mixture was concentrated. The residue was extracted with chloroform and the chloroform layer was washed successively with 1N hydrochloric acid, a saturated aqueous solution of sodium hydrogencarbonate and water and concentrated. Ether was added to the residue and the crystals formed were filtered off to give 1.52 g of 2-{4-(3-ethoxy-2-hydroxypropoxy)phenylcarbamoyl}ethyl methyl sulfide in 67.4%, M.P. 79° to 81° C. cooling the reaction mixture was concentrated The residue was extracted with chloroform the chloroform layer was washed successively with 1N hydrochloric acid a saturated aqueous solution of sodium hydrogencarbonate and water and concentrated Ether was added to the residue the crystals formed were filtered off

Procedure: Dissolved in 4 ml of dimethylformamide were 2.00 g of triethylamine and 2.11 g of 4-(3-ethoxy-2-hydroxypropoxy)aniline. To the solution was added 1.25 g of methylmercaptoacetyl chloride with ice-cooling and the mixture was stirred at room temperature for 12 hours. The reaction mixture was concentrated and the residue was extracted with chloroform. The chloroform layer was washed with water and concentrated. The resulting residue was purified by silica gel column chromatography using a 1:5 ethanol-chloroform mixture, giving 2.85 g of 4-(3-ethoxy-2-hydroxypropoxy)phenylcarbamoylmethyl methyl sulfide in 95.3% yield. cooling The reaction mixture was concentrated the residue was extracted with chloroform The chloroform layer was washed with water concentrated The resulting residue was purified by silica gel column chromatography

Procedure: Using an analogous method to that described in Example 136, but starting from 4-anilino-5-bromo-2-chloropyrimidine (Method 13) and 4-[3-ethoxy-2-(hydroxy)propoxy]aniline (obtained as described in J. Med. Chem., 1998, 41, 330-36), the product was obtained in 21% yield. NMR: 1.10 (t, 3H), 3.42 (m, 2H), 3.45 (q, 2H), 3.75-3.9 (m, 3H), 4.99 (d, 1H), 6.74 (d, 2H), 7.12 (t, 1H), 7.33 (dd, 2H), 7.44 (d, 2H), 7.60 (d, 2H), 8.15 (s, 1H), 9.10 (s, 1H); MS (MH+): 459.3, 461.4. the product was obtained in 21% yield
