실험 절차

To 6-(4-bromo-3-fluorobenzylthio)-3-tert-butoxycarbonyl-7-chloro-2,3,4,5-tetrahydro-1H-benzo[d]azepine (0.210 mg, 0.42 mmol) and dichloro[1,1′-bis(diphenylphosphino)-ferrocene]palladium(II) dichloromethane adduct (17 mg, 0.021 mmol) add 0.5 M 3-methylbutylzinc bromide in THF (4.2 mL, 2.10 mmol). Degas, purge with dry nitrogen, and stir overnight at 80° C. Cool to ambient temperature, dilute with EtOAc, wash with water, dry over anhydrous MgSO4 and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (9:1) to give 3-tert-butoxycarbonyl-7-chloro-6-[3-fluoro-4-(3-methylbutyl)-benzylthio]-2,3,4,5-tetrahydro-1H-benzo[d]azepine as a yellow oil (85 mg, 42%). Use a method similar to the General Procedure 1-4 to give the title compound as a white solid. MS (ES+) m/z: 392 (M+H)+.
