実験手順

2-(4-Chlorophenylthio)nitrobenzene (1.0 g) was dissolved in a mixture of acetic acid (5 ml) and 6N hydrochloride (5 ml), and tin (1.0 g) was added thereto, followed by stirring for six hours at room temperature. After the solvent was removed under reduced pressure, the residue was dissolved in water (50 ml) and a pH of the resultant solution was adjusted to 9-10 with potassium carbonate. The thus-obtained solution was extracted with ethyl acetate. The extracted solution was washed sequentially with water and saturated brine and dried over anhydrous sodium sulfate. Subsequently, the solvent was removed under reduced pressure and the residue was crystallized from ethyl acetate under stirring, to thereby yield the target compound (880 mg) as pale-yellow crystals.
