Reaction Steps

3-(α,α-Dimethylbenzyl)benzenesulphonic acid sodium salt (9.6 g) is dissolved in DMF (16 ml) and cooled to 10° C. Thionyl chloride (12ml) is added dropwise maintaining the temperature below 20° C. The mixture is allowed to warm to room temperature and stirred one hour. The solution is poured onto ice/water (100 ml) and the mixture is extracted with ether (3×8 ml). The combined extracts are dried (MgSO4) and the solvent evaporated to give pale yellow waxy crystals which are dissolved in hexane (200 ml) and decolourised (charcoal). Evaporation produces white crystals of 3-(α,α-dimethylbenzyl)benzenesulphonyl chloride which are dried at room temperature under vacuum, m.p. 47.5°-49° C.
