実験手順

6-tert-Butyl-5-thiocyanato-2,3-dihydro-1H-indole (prepared in Example JJ; 4.5 g, 19 mmol) was taken in CH2Cl2 (50 mL) and treated with 4-cyanophenylsulfonyl chloride (3.91 g, 19.4 mmol) and pyridine (5 mL). The reaction mixture was stirred overnight, quenched with saturated NaHCO3 solution, and diluted with EtOAc. The organic layer was separated, dried (MgSO4), and concentrated. The crude product was purified by flash chromatography (20%-75% EtOAc in hexanes as eluents). MS(APCI): 397 (M+).
