実験手順
When 7-bromo-3(R,S)-tert-butoxycarbonyl-1-ethyl-8-methoxy-2,3,4,5-tetrahydro-1H-1-benzazepine-2-one was treated with bromine in MeOH at ambient temperature, bromination occurred at 3-position of the 1-benzazepine-2-one ring system. In addition, a transesterification due to the presence of methanol was observed which resulted in a formation of 7-bromo-3(R,S)-methoxycarbonyl-1-ethyl-8-methoxy-2,3,4,5-tetrahydro-1H-1-benzazepine-2-one.
