mercaptoheterocycles provided the corresponding 2-nitro-5-[(heterocyclic)thio]benzonitriles. Reduction to the amine followed by cyclization with chloroformamidine hydrochloride afforded a series of 2,4-diamino-6-[(hetero-cyclic)thio]quinazolines. Bromination, oxidation, and amidine formation were accomplished with 2,4-diamino-6-[(4-phenyl-2-thiazolyl)thio]quinazoline (23) to provide additional analogs. Several of
