Participants

Reaction Steps

To a solution of N-[2,2-dimethyl-4-(3-nitrophenyl)-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-7-yl]methanesulfonamide (compound obtained in Example 146; 240 mg) in methanol (5 mL)-tetrahydrofuran (5 mL) was added 10% palladium-carbon (100 mg), and the mixture was stirred at room temperature under atmospheric pressure of hydrogen for 2 hours. The reaction mixture was filtered, and the filtrate was concentrated in vacuo to give N-[4-(3-aminophenyl)-2,2-dimethyl-3-oxo-3,4-dihydro -2H-1,4-benzoxazin-7-yl]-methanesulfonamide as a colorless powder.
