Procedure
To an ice-cooled solution of ethyl (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(4-methoxybenzyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylate (360 mg) in dichloromethane (2 ml) was added anisole (11.0 ml) and TFA (2.0 ml), the mixture was stirred at 20° C. for 1 hour. The mixed solution was poured into a mixture of water (20 ml) and AcOEt (20 ml). The pH of the aqueous layer was adjusted to ca.9 with NaHCO3. The organic layer was separated, washed with brine, dried over sodium sulfate and evaporated under reduced pressure to give ethyl (2E)-3-(6-{[(3R)-1-(4-methoxybenzyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylate as syrup (295 mg).
