실험 절차

A suspension of 5-naphtylbarbituric Acid (0.2 g) in 1.5 ml of 95% ethanol, cooled at 0° C. and kept under stirring, is added dropwise with 48% hydrobromic acid (0.5 ml) and successively with 4.4 μl of bromine. After 4 hours under stirring at room temperature the solid is filtered and washed with water, then it is dried under vacuum at 40° C. overnight. 0.25 g of the product are obtained.
