Acetic Anhydride → HCID 66604128, compound

Participants

Reaction Steps

A catalytic amount of 4-dimethylaminopyridine was added to a mixture of {8-(3,4-difluorobenzyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-8-yl}methanol (80.0 mg), acetic anhydride (19.4 μL), triethylamine (28.6 μL) and THF (1 mL) under ice-cooling. The reaction mixture was stirred at room temperature for 1 hr, and diluted with ethyl acetate, and the mixture was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (72.5 mg).
