실험 절차
A 100 ml 3-necked oven dried flask is equipped with a magnetic stirring bar and a CaCl2 -Drierite drying tube and is charged with 4,4'-thiodiphenol (5.3 grams, 24.3 mmol), benzenesulfonyl chloride (6.5 ml, 50.9 mmol), 4-dimethylaminopyridene (0.59 grams, 4.8 mmol), and anhydrous pyridine (40 ml). The mixture is stirred at ambient temperature for 18 hours, and at reflux for 4 hours, then is poured into ice-cold water (100 ml) with vigorous stirring, and the yellow oil that separates is extracted into CH2Cl2 (100 ml), and washed with water (100 ml). Drying (MgSO4), filtration and concentration affords a yellow oil. Purification by filtration through a column packed with flash grade silica gel (5"×2" i.d.), eluting with CH2Cl2 (ca. 0.5 l), gives after solvent removal under vacuum 11.8 grams (98 percent yield) of the title compound as a faintly yellowish, thick glass material.
