実験手順
A solution of ethyl (2E)-3-(5-chloro-6-{[(3R)-1-(3-methylbenzyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylate (820 mg) and 1N NaOH solution (4.1 ml) in MeOH (20 ml) was stirred at 80-85° C. for 2 hours. The reaction mixture was evaporated in vacuo and the residue was dissolved in a mixture of AcOEt and brine. The aqueous solution was adjusted to PH 5.4 with 5% HCl solution and extracted with THF and AcOEt. The solvent was evaporated in vacuo and The precipitate was washed with n-hexane to give (2E)-3-(5-chloro-6-{[(3R)-1-(3-methylbenzyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid (410 mg).
