Potassium Carbonate → HCID 16679489, compound

Participants

Reaction Steps

To a solution of Example 113A (250 mg, 0.597 mmol) in dimethylformamide (7 ml) was added potassium carbonate (165 mg, 1.194 mmol) and bromoacetamide (124 mg, 0.896 mmol). The reaction mixture was stirred at room temperature for 16 hours then poured onto ice water. The aqueous mixture was extracted with dichloromethane. The organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated. The residue was purified by flash column chromatography using dichloromethane/methanol (80:20) to give the title compound (109 mg).
