Interaction of aryl/alkyl isothiocyanates and a-anilino benzylnitrile has been found to afford the corresponding 5-amino-4-phenyl-3-aryl-2-aryl/alkylimino thiazolines. These have been characterised. The reaction is found to be a general one. The thiazolines on hydrolysis with alkali afford hydrogen sulphide, benzaldehyde along with nonreacted products. Formation of these products, obtained by the hydrolysis, has been confirmed by thin layer chromatography.
