Procedure

To a solution of ethyl (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylate (225 mg, 0.51 mmol) in EtOH (2.5 mL) was added 1N sodium hydroxide solution (1.0 mL) at ambient temperature and the mixture was allowed to stand for 18 hrs. The reaction mixture was adjusted to PH 5.0 with 1 mol/L hydrochloric acid and evaporated in vacuo to give (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid.
