실험 절차

4-Benzyl-3-methylthio-5-sulfamylbenzyl alcohol (10 g; prepared as described in Example 1) is while stirring added in portions to acetic acid saturated with dry hydrogen bromide (50 ml), and the mixture is stirred for 24 hours. The resulting solution is diluted with water (100 ml) and cooled to precipitate crude 4-benzyl-3-methylthio-5-sulfamylbenzyl bromide. After recrystallization from methanol it is obtained with a melting point of 149°-150° C.
