Reaction Steps

To a stirred solution of 1-(2-bromo-ethylsulfonyl)-2-trifluoromethyl-benzene (5.4 g, 19 mmol) in dichloromethane (50 ml) was added triethylamine (4.66 ml, 34 mmol). The reaction mixture was heated under reflux conditions to 50° C. for 12 h. The solvent was removed under reduced pressure and the residue was purified by column chromatography (silica gel, EtOAc/heptane) to yield the title compound (3.68 g, 16 mmol; 69%) as off-white semi-solid. MS (ESI): m/z=254.1 [M+NH4]+.
