Abstract

5‐Amino‐1__H__‐imidazole‐4‐carboxamide hydrochloride has been converted into a series of 2‐methyl‐6‐(arylamino)purines 3 via 5‐acetylamino‐1__H__‐imidazole‐4‐carboxamide hydrochloride (1) which was heated with phosphorus pentoxide, triethylamine hydrochloride, and an appropriate substituted aniline at 180°C.
