Reaction Steps

A mixture of 4 g (28.8 mmol) 3-methyl-4-methoxy pyridine N-oxide (prepared according to the method described in Kohl, Bernhard et al; J. Med. Chem.; 1992; 1049-1057) and 1.1 mg of 5% palladium on charcoal in 50 ml of methanol is hydrogenated at 20 atms at room temperature for 12 hours (2*6 hours). Filtration through celite, and evaporation gave 3.2 g (90%) of a light green oil.
