A solution of 1.46 g of phenyl N-(3-chlorophenyl)carbamate in 15 ml of tetrahydrofuran was added to a solution of 1.92 g of N-benzyl-n-butylamine in 20 ml of tetrahydrofuran and the mixture stirred under reflux for hours. The mixture was diluted with hexane and the precipitate collected by filtration. Recrystallization from pentane afforded 1-benzyl-1-(n-butyl)-3-(3-chlorophenyl)urea, m.p. 69°-70° C.
