Chloroacetyl chloride → HCID 178436788, compound

Participants

Reaction Steps

To a cold (0° C.) solution of compound of example 52 (0.100 g, 0.434 mmol) in THF (5 mL), was added triethylamine (0.065 g, 0.65 mmol) and chloroacetylchloride (0.073 g, 0.65 mmol), and the reaction mixture was stirred at room temperature for a period of 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, 5% methanol in chloroform as an eluent) to obtain the title compound.
