実験手順

To a sol. of compound 4-{4-[2-(2,6-Dichloro-4-methylphenoxy)ethoxy]phenyl}piperidine-1,3-dicarboxylic acid 1-tert-butyl ester 3-methyl ester (0.21 g, 0.38 mmol) in MeOH (2 mL) under Ar was added NaOMe (6 mg, 0.11 mmol). The mixture was stirred for 3 days at 70° C. Water was added, and the mixture was extracted with EtOAc. The org. phase was washed with brine, dried over MgSO4, filtered, and the solvents were removed under reduced pressure. The title compound (150 mg, 72%) was not further purified. LC-MS: tR=1.18 min, ES+=538.32.
