실험 절차

tert-Butyl 1,4,5,6-tetrahydroazepino[4,5-b]indole-3(2H)-carboxylate (0.170 g, 0.594 mmol) and 2-chloroethyl phenyl sulfoxide (0.225 g, 1.20 mmol, 2.0 equiv.) was dissolved in DMF (10 mL) at rt. NaH (0.100 mg, 2.5 mmol, 4.21 equiv., 60% dispersion) was added, then the reaction mixture was stirred for 3 h. The reaction was quenched with a saturated aqueous NH4Cl solution and partitioned between water and CH2Cl2. The aqueous layer was extracted with CH2Cl2 (3×). The combined organic layers were concentrated and the residue was dissolved in EtOAc, dried over MgSO4, filtered, and concentrated. The crude product was chromatographed (Biotage 12m SiO2 column, eluted with a 20% to 30% EtOAc in hexane gradient) to give tert-butyl 6-[2-(phenylsulfinyl)ethyl]-1,4,5,6-tetrahydroazepino[4,5-b]indole-3(2H)-carboxylate.
