A mixture of ethyl (2Z)-3-(5-chloro-6-{[(3R)-1-cyclopentyl-3-pyrrolidinyl]amino}-3-pyridinyl)-2-fluoroacrylate (710 mg) and 1N NaOH solution (3.8 ml) in MeOH (20 ml) was stirred at 75-80° C. for 2 hours. To the reaction mixture was added 1N HCl solution (3.8 ml) and the resultant solution was evaporated in vacuo and the residue was dissolved in a mixture of MeOH and toluene and evaporated in vacuo and the residue was dried to give (2Z)-3-(5-chloro-6-{[(3R)-1-cyclopentyl-3-pyrrolidinyl]amino}-3-pyridinyl)-2-fluoroacrylic acid (658 mg).
