실험 절차

A solution of benzylamine (8.18 g) in benzene (100 ml) was added dropwise to a suspension of 8,9-dihydro-3-nitro-5H-benzocyclohepten-5-one (15.51 g) in ethanol (155 ml) at ambient temperature over 20 minutes. The resulting mixture was stirred at the same temperature for 3 hours 30 minutes, allowed to stand at the same temperature overnight, and filtered. The filtrate was evaporated in vacuo to afford 7-benzylamino-3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-one (25.41 g) as a dark brown oil.
