Reaction Steps

1-[(4-Cyano-1-oxoindan-2-yl)]imidazole-2-carboxamide can be obtained in the following way: a solution of 1.5 g of ethyl 1-[(4-cyano-1-oxoindan-2-yl)]imidazole-2-carboxylate in 130 ml of methanol is kept saturated for one hour at a temperature in the region of 20° C. with a stream of gaseous ammonia. The reaction mixture is then concentrated to dryness under reduced pressure (15 mm Hg; 2 kPa) at 50° C. 1.2 g of 1-[(4-cyano-1-oxoindan-2-yl)]imidazole-2-carboxamide are thus obtained, which product melts at 216° C.
