Reaction Steps

To a solution of 5-Bromo-5-decylbarbituric Acid (0.619 g) in 1.3 ml of dimethylsulfoxide, kept under stirring at 0° C., a solution of 0.93 g of N-(2-hydroxyethyl)piperazine in 0.7 ml of dimethylsulfoxide is added dropwise, then the reaction is stirred at room temperature for 1 hour. The mixture is then cooled to 0° C. and added with 30 ml of water. A white solid separates, which is kept under stirring for 1 hour, then is filtered and dried under vacuum at 50° C. 0.309 g of the product are obtained, m.p. 181-182° C.
