Reaction Steps

Platinum oxide (0.146 g, 0.65 mmol) was added to a stirred solution of 3-(4-nitro-1H-benzoimidazol-2-yl)-4-[(pyridin-2-ylmethyl)-amino]-1H-pyridin-2-one in methanol (12 ml) and tetrahydrofuran (12 ml). The reaction was purged with nitrogen three times and the atmosphere replaced with hydrogen and the reaction stirred at room temperature. After 72 hours the reaction was recharged with platinum oxide (0.146 g, 0.65 mmol) and hydrogen and stirred for a further 24 hours. The reaction was filtered through Celite and the filter cake washed with tetrahydrofuran and methanol. The solvent was concentrated under reduced pressure to give the desired crude aniline (0.610 g, 113%), which was used without further purification.
