Reaktionsschritte

A mixture of (6-chloro-4-(methylamino)pyridin-3-yl)methanol (4.2 g, 24.7 mmol) and manganese(IV) oxide (active, 25.8 g, 296.6 mmol) in dichloromethane (50 mL) and THF (50 mL) was stirred at RT overnight. LCMS showed the reaction was completed. The solid was filtered off, and the filtrate was concentrated to afford the title compound (3.7 g, crude) as a light yellow solid, which was directly used in the next step without further purification. MS (ES+) C7H7ClN2O requires: 170, 172. found: 171, 173 [M+H]+.
