    • Conditions required for the amidine exchange implicated in such reactions are generally strenuous and the use of amidines other than formamidine have been studied relatively little [15a‐c]. Benzamidine has been condensed with 2,4‐diamino‐5‐cyano‐6‐dimethylaminopyridine to give a 7‐phenylpyrimido[4,5‐d]pyrimidine [15a] and acetamidine similarly reacts with 3‐amino‐4‐cyano‐5‐methylpyrazole to give 4‐amino‐3,6‐dimethylpyrazolo[3,4‐d]pyrimidine [15b]: J.

    • This method is akin to an early report of the formation of 2‐alkyl‐4‐thionoquinazoline by the treatment of anthranilonitrile with an acid anhydride and sodium sulfide. That method involved in situ acylation of the amino group, conversion of the nitrile to the thioamide and condensation to the thioquinazoline as a one‐pot conversion

    • This method (which has received little, if any, attention to date) appears to be an attractive alternative to the conventional set of conversions hydroxy → chloro → amino in 4‐substituted pyrimidines [19] whenever the corresponding thione is readily accessible. The scope of this approach to amino derivatives from this and other fused pyrimidinethione systems is under investigation.
