A study of nitrogen- and sulfur-containing heterocycles

The reduction of -cyanoacylurethanes in an aqueous medium in the presence of hydrochlorides of aromatic amines and Raney nickel has given -arylaminoacryloyl-and -alkyl--arylaminoacryloylurethanes which have been converted by heating with 10 % aqueous caustic alkalis into 1-aryl-and 5-alkyl-1-aryluracils.For Communication X, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, Vol. 6, No. 8, pp. 1088–1091, August, 1970.
