Chloroacetyl chloride → HCID 25184913, compound

Participants

Reaction Steps

To a cool (0° C.) solution of compound of example 58 (0.04 g, 0.14 mmol) in THF (3 mL) was added triethylamine (0.021 g, 0.21 mmol) and chloroacetylchloride (0.023 g, 0.21 mmol), and the reaction mixture was stirred at room temperature for 30 minutes. THF was removed under reduced pressure, and reaction mixture was quenched with water and extracted with ethyl acetate (3×10 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated to obtain the crude product, which was purified by column chromatography (silica gel, 50% ethyl acetate in petroleum ether as an eluent) to obtain the title compound.
