Title:
MANUFACTURE OF SUBSTITUTED UREA
Document Type and Number:
Japanese Patent JPS5452008
Kind Code:
A
Abstract:
Process for preparing urea derivatives of the general formula in which R1, R2 and R3 denote identical or different lower alkyl groups which can optionally be substituted by other radicals such as ether or aryl groups, a heterocyclic radical or chlorine, R1 and R3 in each case represent an alkyl group and R2 represents hydrogen or R1 and R2 are alkyl groups which can optionally be replaced by hydrogen when R3 is an aryl group which is optionally substituted by a hydroxyl, chlorine, methoxy or alkyl group, from carbonyl sulphide and amines.
