Expeditious routes to 4-alkoxyquinazoline-2-carbonitriles and thiocarbamates via N-arylimino-1,2,3-dithiazoles using microwave irradiation☆
Conversion of N-arylimino-4-chloro-5H-1,2,3-dithiazoles into the 4-alkoxyquinazoline-2-carbonitriles and of the aryl isothiocyanates into aryl thiocarbamates, either by conventional thermolysis or by microwave irradiation, are described and directly compared.
