Procedure
To a solution of 65 parts of dimethylcarbamoylisothiocyanate (a compound of formula VI) in 350 parts methylene chloride are added within 10 minutes at 0° C, 50 parts of conc. aqueous ammonia with good agitation. The resulting slurry of crystals is stirred for an additional 15 minutes at 0° C and then filtered to give 70 parts of 1,1-dimethyl-4-thiobiuret (a compound of formula VII), m.p. 184°-185° C.
