반응 단계

Use a method similar to the General Procedure 7 to react 3-tert-butoxycarbonyl-7-chloro-6-dimethylcarbamoylthio-2,3,4,5-tetrahydro-1H-benzo[d]azepine (200 mg, 0.521 mmol) with 4-acetylbenzyl bromide (555 mg, 2.605 mmol). Purify the crude mixture by chromatography on silica gel eluting sequentially with hexane and hexane/EtOAc (9:1, 4:1) to obtain 6-(4-acetyl-benzylthio)-3-tert-butoxycarbonyl-7-chloro-2,3,4,5-tetrahydro-1H-benzo[d]azepine (190 mg, 82%).
