Participants

Reaction Steps

tert-Butyl (trans-4-hydroxycyclohexyl)carbamate (1.0 g, 4.6 mmol) in tetrahydrofuran (20 mL) was stirred with sodium hydride (55 wt % dispersion in mineral oil, 24 mg, 6.4 mmol) and 15-crown-5 ether (965 μL) for 30 minutes under cooling with ice and then with iodomethane (289 μL) at room temperature for 1 hour. Methanol (2 mL) was added to the reaction mixture, and the precipitated solid was removed by filtration. The filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=8/1 (v/v)) to give the title compound (708 mg, yield 67%).
