実験手順

To a suspension of 5-benzylbarbituric acid (1.7 g) in 15 ml of water, cooled to 0-5° C., 1 ml of 48% hydrobromic acid are added followed by the addition dropwise of 0.437 ml of bromine into the reaction mixture. After 1 hour under stirring at a temperature below 10° C. the solid which formed is separated by filtration and washed with water. 2.17 g of the product are obtained. m.p. 164-166° C.
