Benzoyl chloride → HCID 121396295, compound

Participants

Reaction Steps

To a cooled solution of 1-[(3aS,5S,6aS)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxol-5-yl]ethanol (compound 25g, 200 mg, 1.06 mmol) in DCM (8 mL) was added benzoyl chloride (178 mg, 1.28 mmol) and DMAP (259 mg, 2 mmol). After the addition, the mixture was warmed naturally to room temperature and stirred at room temperature overnight. The resulting mixture was diluted with EtOAc and washed with a saturated aqueous solution of NH4Cl. The organic layer was dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography on silica gel (eluting with 1:3 EtOAc in petroleum ether) to afford 170 mg of 1-[(3aS,5S,6aS)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxol-5-yl]ethyl benzoate (compound 25h).
