Procedure

2 g of the thus obtained 2-hydroxymethyl-4-acetylaminopyridine were suspended in 400 ml of dichloromethane, mixed with 6 g of MnO3 refluxed for 26 hours. The MnO2 was then filtered hot and the dichloromethane solution rotated n to dryness. 1.5 g of 4-acetylaminopyridine-2-aldehyde were obtained.

Workup

  1. temperaturerefluxed for 26 hours
  2. filtrationThe MnO2 was then filtered hot
