반응 단계
To a mixture of (R)-tert-butyl 3-((R)-(3-chlorophenyl)(hydroxy)methyl)piperidine-1-carboxylate (0.1964 g, 0.60 mmol, 1.0 equiv) and 60% NaH in oil (0.753 g, 18.8 mmol, 31 equiv) in THF (15 mL) was added (2-bromoethoxy)-tert-butyldimethylsilane (2.042 g, 8.5 mmol, 14 equiv). The resulting mixture was heated at 80° C. for 19 h and then quenched with water, extracted with EtOAc and dried over Na2SO4. After the solvent was removed, the crude product was used in the next step without further purification.
