Reaction Steps
Besides it is known that in the action of cyanogen chloride on dimethylamine under pressure at a temperature of 130° to 180° C. in a water nonmiscible organic solvent 1,1,3,3-tetramethyl guanidine is formed (German Pat. No. 1,958,095). If it is attempted to react cyanogen chloride in a corresponding manner with ammonia to produce guanidine or guanidine hydrochloride there are not obtained satisfactory yields.
