Reaction Steps

1-Cyclohexyl-3-(p-chlorophenyl)thiourea (2.0 g.) was dissolved in absolute ethyl alcohol saturated with ammonia (40 ml.). To this was added yellow mercuric oxide (1.7 g.) and the mixture stirred at room temperature for 16 hours. The mixture was then refluxed 15 minutes to coagulate the fine precipitate of mercuric sulphide, filtered and the clear filtrate evaporated to dryness. The residue was recrystallised from toluene to give 1-cyclohexyl-3-(p-chlorophenyl)guanidine, m.p. 187°-190°.
