Versuchsvorschrift

To a solution of 1,7-naphthyridin-8-amine (600 mg, 4.13 mmol) in DCM (5 mL) was added a solution of O-(mesitylsulfonyl)hydroxylamine (2.7 g, 12.4 mmol) in DCM (10 mL) at 0° C. The mixture was stirred at 0° C. for 2 h. The precipitate was filtered and collected to give 8-imino-1,7-naphthyridin-7(8H)-amine-2,4,6-trimethylbenzenesulfonate as a brown solid (1.2 g, yield 67%). ESI MS: m/z 161.1 [M+H]+.
