실험 절차

A solution of tert-butyl-1-oxa-6-azaspiro[2.5]octane-6-carboxylate (0.7 g, 3.42 mmol) and 2-[(4-methoxyphenyl)methylamino]-2-phenyl-ethanol (800 mg, 3.109 mmol) in ethanol (5 mL) was stirred at 60° C. for 72 hours. The reaction mixture was concentrated in vacuo and purified by silica gel column chromatography using 0 to 10% MeOH in DCM as eluent to yield tert-butyl 4-hydroxy-4-[[(2-hydroxy-1-phenyl-ethyl)-[(4-methoxyphenyl)methyl]amino]methyl]piperidine-1-carboxylate (1.2 g, 82%). ESI-MS m/z calc. 470.6. Found 471.5 (M+1)+; Retention time: 1.45 minutes (3 min run).
