Pyridine → HCID 67314002, compound

Participants

Reaction Steps

To a solution of 43 mg (0.10 mmol) of 5-(3-chlorophenyl)-3-(2,4-dichlorophenyl)-4-[(3-pyridyl)hydroxymethyl]isoxazole in 2 mL of pyridine was added 19 μL (0.20 mmol) of acetic anhydride. The reaction was stirred overnight at room temperature, and then the pyridine was removed under vacuum. The residue was taken up in ethyl acetate, washed with saturated sodium chloride, and the ethyl acetate fraction dried over magnesium sulfate. The drying agent was filtered off, and the ethyl acetate was removed by rotoevaporation. The crude product was purified by preparative thin layer chromatography (prep TLC) to give 35 mg (0.074 mmol) of 5-(3-chlorophenyl)-3-(2,4-dichlorophenyl)-4-[(3-pyridyl)acetoxymethyl]isoxazole.
