実験手順
To the crude 3-tert-butoxycarbonyl-6-(4-bromomethyl-benzylthio)-7-chloro-2,3,4,5-tetrahydro-1H-benzo[d]azepine in anhydrous DMF (1 mL) under nitrogen, add with string sodium methanesulfinate (400 mg, 3.9 mmol), and continue stirring for 30 min at ambient temperature followed by 2 h at 40° C. Add water, extract three times with EtOAc, wash with brine, dry over anhydrous MgSO4, and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (3:1) to give a clear oil that solidifies on standing to a white solid (118 mg, 61%).
