실험 절차

A solution of 4-Chloro-3-nitro-phenol (2.0 g, 11.52 mmol), 4-hydroxythiophenol (1.45 g, 11.52 mmol) and cesium carbonate (11.26 g, 34.56 mmol) in N,N-dimethylformamide (25 mL) was heated to 100° C. for 4 hours. After cooling to room temperature, 1N aqueous Hydrochloric acid (150 mL) was added and the resultant solution extracted with ethyl acetate (2×100 mL), the combined extracts dried over magnesium sulfate, filtered and concentrated under vacuum to provide the crude title compound which was purified by chromatography on silica gel using hexanes/ethyl acetate as eluent to obtain the title product as a bright orange solid (1.35 g, 45%).
