Versuchsvorschrift

20.8 g (0.1 mol) of 5-methyl-1,3-benzodioxole-2-carboxylic acid ethyl ester Example 2b) and 19.2 g (0.125 mol) of phenylsulphinic acid chloride are dissolved in 200 ml of 1,2-dichloroethane and cooled to 5° using an ice-bath. 13.3 g (0.1 mol) of aluminium chloride are introduced in the course of approximately 15 minutes at from 5°-10° while stirring. The mixture is stirred for a further hour in the ice-bath and is then poured out onto ice-water. The resulting emulsion is diluted with 200 ml of dichloroethane and filtered across a layer of a filter aid (for example Hyflo). The filtrate is introduced into a separating funnel and the layers are separated. The organic phase is dried over sodium sulphate, filtered and concentrated to dryness by evaporation. A light brown honey-like product, 5-phenylsulphinyl-6-methyl-1,3-benzodioxole-2-carboxylic acid ethyl ester, is obtained.
