실험 절차

A solution of 4-nitrobenzoyl chloride (1.49 g, 8.0 mmol) in benzene (anhydrous, 10 mL) was added dropwise to 2-aminothiophenol (1.0 g, 8.0 mmol in 10 ml of benzene) at room temperature. The reaction mixture was allowed to stir for 16 hr. The reaction was quenched with water (20 mL). The aqueous layer was separated and extracted with ethyl acetate (3×10 ml). The combined organic layers were dried and evaporated. The crude product was purified with flush column, (hexane:ethyl acetate=85:15) to give 1.5 g (73.2%) of product as light yellow solid.
