Participants

Reaction Steps

A mixture of (6-chloro-5-methyl-4-(methylamino)pyridin-3-yl)methanol (1.4 g, 8.0 mmol) and manganese oxide (2.8 g, 32 mmol) in dichloromethane (100 mL) was stirred at RT for 4 h. LCMS monitored the reaction was completed. The solid was filtered off, and the filtrate was concentrated to get the title compound (1.2 g, crude) as a yellow oil. MS (ES+) C8H9ClN2O requires: 184, 186. found: 185, 187 [M+H]+.
