Abstract
Abstract The bis (methylthio) methylene malononitrile ( 1 ) on treatment with 2-amino pyridine ( 2 ) in N , N -dimethyl formamide (DMF) and anhydrous potassium carbonate, gives 3-cyano-4-imino-2-(methylthio)-4 H -pyrido[1,2- a ]pyrimidine ( 3 ). The latter were further reacted with selected N-, O- and C-nucleophiles such as aryl amines, hetryl amines, substituted phenols and compounds containing active methylene groups.
