反应详情

6-(Cyclohexylamino)-5-nitropyridin-2-ol (0.2 g, 0.843 mmol) was dissolved in methanol (168 mL). Palladium (5% Pd/C, 145 mg, 0.0063 mmol) was added. The reaction was flushed with nitrogen and stirred under a balloon filled with hydrogen for 3 h at room temperature. The reaction was monitored by TLC until the starting materials were consumed. The mixture was filtered through Celite® and concentrated to give the title compound as a dark green solid which was used immediately in next step without further purification.
