Abstract

Double compounds of CC1-disubstituted barbituric acids and 4-dimethylamino-2 : 3-dimethyl-1-phenyl-5-pyrazolone are prepared in the manner described in the parent Specification, using other disubstituted barbituric acids than diethylbarbituric acid. Examples are given of the preparation of double compounds of the pyrazolone with isopropylpropenylbarbituric acid and phenylethylbarbituric acid. Specification 237,590 is referred to.
