Triethylamine → HCID 178482824, compound

Participants

Reaction Steps

Triethylamine (20 μl), 4-dimethylaminopyridine (catalytic amount) and 4-dimethylaminobenzoyl chloride (26 mg) were added to a stirred solution of trans-4-(2,4-bis{[tert-butyl(dimethyl)silyl]oxy}phenyl)cyclohexanol (30 mg) in dry dichloromethane (2 ml) at room temperature under argon. After 24 hr, the solvent was removed under reduced pressure and the residue was partitioned between water (10 ml) and ethyl acetate (20 ml). The aqueous layer was extracted with ethyl acetate (2×20 ml) and the combined organic extracts were washed with brine (10 ml), dried over magnesium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (SiO2, ethyl acetate/petrol, 1:24 v/v) to give the title compound as a white solid (18 mg, 45%); m/z (ES+) 585 (M+H)+.
