Reaction Steps
1-[4-(1,1,2,2-tetrafluoroethoxy)phenyl]piperazine (1.39 g, 0.005 mol) was dissolved in DCM (250 ml) and triethylamine (2.1 ml, 0.015 mol) was added. This was cooled to 0° C. and styrene sulphonyl chloride (CAS Number 52147-97-4, 1.11 g, 0.0055 mol) was added. Allowed to reach ambient temperature and stirred overnight. Washed with H2O and separated off the organic phase. Dried over MgSO4, filtered and evaporated to dryness to an oil which was purified by flash column chromatography (Merck 9385 silica), eluting with 80% iso-hexane/ethyl acetate to yield 1-[(-2-phenylvinyl)sulphonyl]-4-[4-(1,1,2,2-tetrafluoroethoxy)phenyl]piperazine as a yellow solid. Yield 650 mg (25%)
