実験手順

2.0 ml of 65% nitric acid were cautiously added dropwise to 7.1 ml of acetic anhydride at 0° C. This solution was added to a solution of 3.14 g of 2,3,4,5-tetrahydro-1,5,5-trimethyl-2-oxo-1H-1-benzazepine in 9.0 ml of acetic anhydride and 2.8 ml of glacial acetic acid. The reaction mixture was left to stand at room temperature for 3 days and then poured on ice, washed in succession with water, soda solution and water, dried and evaporated. Recrystallization from ethyl acetate/hexane yielded 3.39 g of 2,3,4,5-tetrahydro-1,5,5-trimethyl-7-nitro-2-oxo-1H-1-benzazepine, 113°-115° C.
