Participants

Reaction Steps

To a solution of 5-(3-cyano-benzyloxy)-2-cyclopropyl-6-methyl-nicotinic acid methyl ester (184) (500 mg, 1.55 mmol) in methanol (10 mL), added aqueous sodium hydroxide (10 mL, 1N) and stirred at room temperature for 3 days. Hydrochloric acid (5 mL, 12N) was added to the reaction mixture and methyl alcohol was evaporated. The precipitate was collected by filtration to give 5-(3-cyano-benzyloxy)-2-cyclopropyl-6-methyl-nicotinic acid (185) (300 mg, 63% yield).
