Sodium hydride → tert-butyl-4-[(1R,2R)-2-({[4-(methylsulfonyl)benzyl]oxy}methyl)cyclopropyl]piperidine-1-carboxylate

참여 물질

반응 단계

4-(Methylsulfonyl)benzyl alcohol (1.0 g, 5.4 mmol) was dissolved in DMF (12 mL), and sodium hydride (60 wt % dispersion in oil, 320 mg, 8 mmol) was added. The iodide from step A (2.35 g, 6.4 mmol) in DMF (12 mL) was added and the resulting solution was stirred at RT for 15 h. The solution was quenched with sat. NH4Cl, and EtOAc. The organic layer was washed with water and brine. The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was purified via silica gel column chromatography (2/1 hexanes/EtOAc) which provided the title compound.
