実験手順

To a solution of 1,5-naphthyridin-2-amine (2.0 g, 13.8 mmol) in DCM (10 mL) was added a solution of O-(mesitylsulfonyl)hydroxylamine (8.9 g, 41.3 mmol) in DCM (20 mL) at 0° C. The mixture was stirred at 0° C. for 3 h. The precipitate was filtered and collected to give the crude product as a yellow solid (4.2 g, yield 85%). ESI MS: m/z 161 [M+H]+.
