Sodium hydride (60% in mineral oil, 278 mg, 6.96 mmol) was suspended in THF (5 mL) and cooled to 0° C. trans-tert-Butoxy-N-(4-hydroxycyclohexyl)carboxamide (1 g, 4.64 mmol) and 15-crown-5 (0.965 mL, 4.88 mmol) were added and the reaction mixture was stirred at 0° C. for about 30 minutes. Iodomethane (0.289 mL, 4.64 mmol) was added and the reaction stirred at 0° C. for about 1 hour after which the LCMS showed it was complete. The reaction was quenched with methanol, the solvents removed in vacuo and the crude purified by column chromatography (SiO2, 8:2 n-hexanes/ethyl acetate) to afford 642 mg of the methyl ether. ES-MS: 230 (M+1).
