반응 단계

Sulfuryl chloride (0.6 ml) was added to a solution of ((4-bromothiophen-2-yl)methoxy)(tert-butyl)diphenylsilane (2.0 g) in CH3CN (20 ml) at room temperature. The mixture was stirred at room temperature overnight. The mixture was quenched with saturated sodium thiosulfate solution (40 ml) at room temperature and extracted with EtOAc. The organic layer was separated, washed with water and brine successively, dried over MgSO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (182 mg) as a brown oil.
