Reaction Steps

To a solution of ethyl 5-cyano-6-methyl-4-(3-nitrophenyl)-2-pyridinecarboxylate (2.75 g) in ethanol (30 ml) was added a solution of sodium hydroxide (0.37 g) in water (6 ml). After the mixture was stirred at ambient temperature for 1.5 hours, the reaction mixture was adjusted to pH 2 with 6N hydrochloric acid. The resulting precipitates were filtered off, washed with water, and dried to give 5-cyano-6-methyl-4-(3-nitrophenyl)-2-pyridinecarboxylic acid (2.4 g).
