Reaction Conditions

Reaction Steps

A mixture of ethyl (2E)-3-{6-[(1-benzyl-3-pyrrolidinyl)amino]-3-pyridyl}-acrylate (830 mg) and 1N NaOH solution (4.7 ml) in MeOH (20 ml) was stirred at 70-75° C. for 2 hours. The reaction mixture was evaporated in vacuo, and the residue was dissolved with saturated NaCl solution (20 ml). The solution was adjusted to pH6.0 with aq. HCl, and the precipitate was collected by filtration to give (2E)-3-{6-[(1-benzyl-3-pyrrolidinyl)amino]-3-pyridyl}-acrylic acid (700 mg)
