1-cyclohexyl-3-phenylurea

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

Procedure: 5.26 g (0.02 mole) of(2-methyl 1-phenyloxy 2-hydroxy propyl)-cyclohexylamine is dissolved in 300 ml of benzene. 2.38 g (0.02 mole) of phenylisocyanate were added. Slight heating was observed as well as the appearance of a solid. It was heated under reflux for 1 hour. After cooling, it was filtered and the product was recrystallized in ethanol. Melting point 164° C. Slight heating It was heated under reflux for 1 hour After cooling it was filtered the product was recrystallized in ethanol

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

Procedure: A mixture of 1.0 g cyclohexylamine and 5 ml aceton was added dropwise to a suspension of 1.5 g phenylcarbamoyl-benzoic acid sulfimide with 20 ml aceton, under stirring. The reaction mixture was stirred for 80 minutes at room temperature, then diluted with 150 ml water. The precipitated solid product was cooled, filtered, washed with water and dried. 1.0 g 1-phenyl-3-cyclohexylurea was obtained with a melting point of from 182° to 184° C. The reaction mixture was stirred for 80 minutes at room temperature The precipitated solid product was cooled filtered washed with water dried
