Reaction Steps
19 g of tetrakis (bromomethyl)ethylene and 9 g of p-toluene sulfonamide were disolved in 220 ml of dimethylformamide. 30 g of anhydrous potassium carbonate was added and then stirred at room temperature for 20 hours. Thereafter solvent was removed by vacuum distillation. 50 ml of ethylacetate was added to obtain solid product, and solid product was purified by silica gel column chromatography. 12 g of the title compound was obtained (yield 60%).
