実験手順

To a mixture of tert-butyl 4-hydroxy-4-[[(4-methoxyphenyl)methylamino]methyl]piperidine-1-carboxylate (1.06 g, 3.01 mmol) and diisopropylethylamine (1 mL, 5.74 mmol) in DCM (15 mL) at 0° C. was added 2-chloro-2-phenyl-acetyl chloride (654 mg, 3.46 mmol) and the reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was concentrated in vacuo and the residue was purified by silica gel column chromatography using 0-100% EtOAc/DCM as eluent to give tert-butyl 4-[[(2-chloro-2-phenyl-acetyl)-[(4-methoxyphenyl)methyl]amino]methyl]-4-hydroxy-piperidine-1-carboxylate (1.11 g, 73%) as a pale yellow oil. ESI-MS m/z calc. 502.2. Found 503.5 (M+1)+; Retention time: 1.90 minutes (3 min run).
