実験手順

N-Methyl-5-nitro-3-pyridin-2-yl-3,4-dihydro-2H-1,4-benzoxazine-3-carboxamide (25 mg, 0.080 mmol) was dissolved in methanol (5 mL) in a Parr bottle and degassed with nitrogen, followed by addition of palladium (10% on carbon) (5 mg, 0.05 mmol). The reaction vessel was charged to 50 PSI hydrogen and shaken for 2 h. The reaction mixture was filtered and concentrated in vacuo to give crude 5-amino-N-methyl-3-pyridin-2-yl-3,4-dihydro-2H-1,4-benzoxazine-3-carboxamide (0.005 g. 100%). LCMS calculated for C15H17N4O2 (M+H)+: m/z=285.1. found: 285.0.

後処理
