1-phenyl-3-propan-2-ylurea

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

Procedure: A solution of 0.75 g i-propylamine with 5 ml aceton was added dropwise to a suspension of 1,5 g phenylcarbamoyl-benzoic acid sulfimide with 10 ml acetone, under stirring. The reaction mixture was stirred for 30 minutes at ambient temperature, then diluted with 50 ml water and cooled. The 0.75 g crystalline 1-phenyl-3-i-propylurea was isolated by filtration (melting point: 158°-160° C.). The reaction mixture was stirred for 30 minutes at ambient temperature cooled
