Abstract
A method for preparing the 2- (aromatic lower) -4-metathiazanones of the formula: ** (See formula) ** wherein Ar represents a lower aromatic radical, R represents a member selected from the group encompassing hydrogen, a lower aliphatic hydrocarbon radical, containing an aliphatic carbon atom bonded to the ring nitrogen atom, a lower cycloalkyl radical, a lower cycloalkohilalchol radical and a lower (monocyclic-aromatic monocyclic) - (lower alkyl) radical and wherein R1, R2 and R3 represent members selected from the group encompassing hydrogen and lower alkyl radicals, which consists of heating a mixture formed by a (lower aromatic) -aldehyde of the formula Ar-CHO, beta-mercaptopropionic acid having the formula HS-CH (R1) C (R2) (R3) COOH and a member selected from the group encompassing an aminating agent and a primary amine of the formula R-NH2.
