Abstract

Synthesis of 1-Substituted 5-Aminoimidazole-4-carbaldehydes and 8-Amino-1-(2-fluorobenzyl)imidazo [4',5':5,6]pyrido[2,3-d]pyrimidine. -Various title compounds (III) are prepared as shown. The synthetic utility of the products is proved by transformation of (IIIe) to the pharmaceutically interesting ring system (VIII). -(BOOTH, BRIAN L.; CARPENTER, ROBERT A.; MORLOCK, GABY; MAHMOOD, ZAHID; PRITCHARD, ROBIN B.; Synthesis (2001) 16, 2393-2396; Dep.
