実験手順

To a solution of (E)-2-{4-[2-(2-tert-butoxycarbonylamino-phenylcarbamoyl)-vinyl]-phenyl}-3-(1-methyl-piperidin-4-yl)-propionic acid methyl ester (52.1 mg, 10 mmol) in MeOH/H2O (4:1) (2 mL), LiOH (24 mg, 100 mmol.) was added. After the solution was stirred at room temperature for 5 h, the solution was neutralized with 2N HCl to pH 5-6. The mixture was evaporated to dryness under reduced pressure, then EtOAc (10 mL) was added. The organic layer was washed with brine, dried with Na2SO4, filtered, and evaporated to obtain a yellow solid product without further purification. MS: calc'd 508 (MH+), exp 508 (MH+).
