Abstract

1,129,356. Substituted thiourea derivatives. AGFA GEVAERT A.G. 15 Aug., 1966 [28 Aug., 1965], No. 36393/66. Heading C2C. [Also in Division G2] The compound of formula is prepared by reacting N<SP>1</SP>,N<SP>1</SP>-dimethyl - N-(4 - nitrophenyl) thiourea (obtained from 4-nitrophenyl mustard oil and dimethylamine) with morpholine in the presence of sodium hypochlorite. The compound of formula is prepared by reacting N-phenyl-N1 N<SP>1</SP>-dimethyl-thiourea with dimethylamine in the presence of sodium hypochlorite.
