Benzyl acetate → HCID 57974088, compound

Participants

Reaction Steps

To a 0° C. solution of (5R)-5-(3,5-difluorophenyl)thiomorpholin-3-one (247 mg, 1.08 mmol, prepared by analogy to Intermediate 2) in THF (8.0 mL) was added sodium hydride (38 mg, 1.5 mmol, 95% by weight). After 5 minutes, the ice bath was removed and the reaction was allowed to warm to ambient temperature. Once hydrogen gas evolution had ceased, as judged by an oil bubbler, the reaction mixture was cooled to 0° C., prior to the introduction of benzyl acetate (272 mg, 1.19 mmol). After 5 minutes, the ice bath was removed and the reaction was stirred for 15 hours. The bulk of the THF was removed under reduced pressure. The residue was then diluted with water and ether. The aqueous layer was extracted once with ether and the combined organics were washed with saturated brine. The organics were then dried over sodium sulfate, filtered, and concentrated in vacuo to give a residue that was purified by silica gel chromatography, eluting with a gradient of MeOH:DCM-0.5:99.5 to 5:95, to give the title compound. MS: m/z=378 (M+1).
