Procedure

To a solution of 2-(6-chloro-4-{trans-4-[(dimethylamino)methyl]cyclohexylamino}-1,5-naphthyridin-3-yl)-2-oxoethyl acetate (90 mg, 0.22 mmol) in methanol was added freshly ground potassium carbonate (90 mg, 0.65 mmol) and the reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was diluted with satd. aq. sodium bicarbonate and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate, filtered and the filtrate was concentrated. The residue was purified by column chromatography (silica, dichloromethane/methanol) to afford the desired product (18 mg, 22%) as a yellow solid. ESI MS m/z 377 [M+H]+.
