실험 절차

Into a triple-necked flask of a liter, provided with a magnetic stirring system, with a thermometer, with a calcium chloride trap and with a dropping funnel, were introduced into the cold at about 0° C. and successively 138 g (1 mole) of veratrol then drop by drop 135 g (1 mole) of sulfuryl chloride. When the addition was terminated, the reaction medium was brought to room temperature, then after standing one hour was distilled under reduced pressure.
