실험 절차

14.6 g of phenylsulfenyl chloride was added dropwise to a cooled, stirred solution of 14.3 g of Compound 1 in 250 ml of pyridine. The mixture was allowed to stand overnight at room temperature, then excess pyridine was recovered on a rotary evaporator. The residue was treated with 250 ml of water and the mixture extracted with methylene chloride. The combined extracts were dried and the solvent evaporated to give a crystalline solid which was triturated with ethyl acetate, then ethanol, to yield 25, as a yellow solid, melting point: 170° - 173°.
