Reaction Steps

In a 50 mL round bottom flask, a mixture of 0.5 g of maleimide, 0.61 g of divinylsulfone and 10 g of 1,4-dioxane was heated to 40-50° C. and stirred. To the reaction solution was added 0.67 g of 40% aqueous tetrabutylammonium hydroxide solution. Subsequently, the mixture was stirred at 40-50° C. for 3 more hours. After stopping stirring, the reaction solution was cooled to room temperature and precipitated and dispersed in 100 mL of methanol. The resultant precipitate was filtered, redispersed in a large volume of clean water, filtered again and washed to remove salt. Then, the product was redispersed in 50 mL of methanol, filtered and dried to obtain 0.94 g of N-vinylsulfonylethylmaleimide (yield=61%)
