実験手順
To a 500 ml Parr hydrogenation flask was added 5% platinum on carbon (1.432 g) and a solution of 1-[(2,3-dimethyl-5-nitro-6-phenoxypyridin-4-yl)amino]-2-methylpropan-2-ol in 90/10 toluene/isopropanol (105 ml). The flask was evacuated until the solvent bubbled, and hydrogen was pressured into the flask at 207 kPa. After three evacuation cycles the flask was pressurized with hydrogen to 345 kPa and mixed on a shaker for about 2 hours. The pressure was released, and thin layer chromatography (TLC) monitoring of the reaction mixture indicated complete reaction. The reaction mixture was filtered, and the solvent was removed under reduced pressure. The resulting product was used in the next step.
