Abstract
5 : 5-Disubstituted barbituric acids and their N-substitution products, in which one of the 5-substituents is the furfuryl group and the other is either a phenyl or a furfuryl group, are prepared by the methods described in the parent Specification. The products are useful as hypnotics. Examples describe the preparation of (1) 5-phenyl-5-furfuryl-barbituric acid by treating sodium phenylbarbiturate with furfuryl bromide in the presence of copper sulphate; (2) 5 : 5-difurfuryl-barbituric acid by interaction of barbituric acid with two molecular proportions each of furfuryl chloride and alkali.
