Reaction Steps

A mixture of ethyl 1-(4-carboxyphenyl)-5-[4-(methylsulfonyl)phenyl]pyrazole-3-carboxylate (3.9 g) and sodium methoxide (3 g) in formamide (40 ml) was stirred at 45° C. for 3 hours. The mixture was poured into a mixture of ice-water and hydrochloric acid. The precipitates were collected, washed with water, and dried to give crystals of 1-(4-carboxyphenyl)-5-[4-(methylsulfonyl)phenyl]pyrazole-3-carboxamide (3.2 g).
