Procedure

To a stirred solution of ethyl (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(diphenylmethyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylate (205 mg) in methanol (5 mL) was added 1N-NaOH solution (0.8 mL). The mixture was stirred at ambient temperature for 12 hours. Methanol was evaporated in vacuo and the aqueous layer was washed with diisopropyl ether. The aqueous layer was acidified by hydrochloric acid to pH 4, and the precipitate was collected and washed with water to give (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(diphenylmethyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylic acid (161 mg) as a white powder.
