Reaction Steps

In an analogous manner to general procedure IV, 1-(2,4-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole2,2-dioxide (3.37 g, 11.9 mmol) was treated with (E)-1,4-dibromobut-2-ene (8.9 g, 41.7 mmol) and cesium carbonate (3.9 g, 11.9 mmol) to give 1-[(2E)-4-bromobut-2-en-1-yl]-3-(2,4-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole2,2-dioxide (3.3 g, 67%) as a clear oil.
