Versuchsvorschrift
To a solution of cyclohexylamine (1.75 g.) in chloroform (15 ml.) was added dropwise with stirring a solution of p-chlorophenylisothiocyanate (3.0 g.) in chloroform (15 ml.) at room temperature. After stirring 3 hours, the white solid was filtered off, washed with a little CHCl3 and recrystallised from toluene to give 1-cyclohexyl-3-(p-chlorophenyl)thiourea, m.p. 179°-180°.
