実験手順

N-[(5-Nitro-3-pyridin-2-yl-3,4-dihydro-2H-1,4-benzoxazin-3-yl)methyl]acetamide (0.040 g. 0.122 mmol) was dissolved in ethanol (5 mL) in a Parr bottle and degassed with nitrogen, followed by addition of palladium (10% on carbon) (10 mg, 0.09 mmol) catalyst. The reaction vessel was charged to 50 PSI with hydrogen, and shaken for 2 h. The mixture was then filtered and concentrated to give crude N-[(5-amino-3-pyridin-2-yl-3,4-dihydro-2H-1,4-benzoxazin-3-yl)methyl]acetamide (0.040 g, 80%). LCMS calculated for C16H19N4O2 (M+H)+: m/z=299.1. found: 299.0.
