Reaction Steps
In an analogous manner to general procedure IV, 1-(2,4-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole2,2-dioxide (2.07 g, 7.3 mmol) was treated with 1-bromo-2-(2-bromoethoxy)ethane (3.2 mL, 25.7 mmol) and cesium carbonate (2.4 g, 7.3 mmol) to give 1-[2-(2-bromoethoxy)ethyl]-3-(2,4-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole2,2-dioxide (1.72 g, 53%) as a white amorphous solid. MS (ES) m/z 368.7 [M+H—SO2]+.
