反応手順

150 mg of platinum oxide was added to 10 ml of a solution of 3-nitro-4-methylaminopyridine (1.5 g) in ethanol. The mixture was stirred under a hydrogen atmosphere at room temperature for 7.5 hours. Platinum oxide was removed by filtration, and the filtrate was concentrated. Thus, 962 mg (yield: 80%) of the intended product was obtained as brown crude crystals.
