Triethylamine → N-(8-Chloro-1,5-naphthyridin-3-yl)-2-methoxyacetamide

Participants

Reaction Steps

A round bottom flask under nitrogen was charged with 8-chloro-1,5-naphthyridin-3-amine (41 mg, 0.23 mmol), triethylamine (64 μl, 0.46 mmol), and dichloromethane (1 mL). To this was added 2-methoxyacetyl chloride (42 μl, 0.46 mmol) dropwise via syringe and reaction allowed to stir overnight at room temperature. Next day reaction mixture was diluted with dichloromethane and washed with aqueous sodium bicarbonate solution. Layers separated and organic layer dried over sodium sulfate to afford yellow oil. This was purified by ISCO silica gel chromatography (2-5% MeOH/DCM) to afford N-(8-chloro-1,5-naphthyridin-3-yl)-2-methoxyacetamide (43 mg, 75% yield) as light yellow solid. MS[M+H]=251.9. Calc'd for C11H10ClN3O2=251.7.
