To a solution of ethyl (2E)-3-(6-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-5-methyl-3-pyridyl)acrylate (366 mg) in MeOH (2 mL) and dioxane (2 mL) was added 1N NaOH aq solution (2.0 mL), and the mixture was stirred at ambient temperature for 3 hours. The pH value of the mixture was adjusted to 7 with 1N HCl, and the solvent was removed in vacuo. Obtained solid was suspended in toluene and the residual water was geotropically removed to give (2E)-3-(6-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-5-methyl-3-pyridyl)acrylic acid and the crude product was used in next reaction without further purification.
