Abstract
The calcium or magnesium salts of double compounds of C-substituted barbituric acids with bile acids are prepared by combining the barbituric acid with the calcium or magnesium salt of a bile acid, or by reacting a mixture of the two acids with calcium or magnesium oxide in water. The products are useful as soporifics. Examples describe the interaction of (1) phenylethylbarbituric acid and dehydrocholic acid with calcium oxide; (2) N-methyl-C : C-cyclohexenylmethylbarbituric acid, oxycholenic acid and calcium oxide; and (3) diethylbarbituric acid, dehydrocholic acid and magnesia. The formul of the products are given. Reference is also made to the calcium double salt of N-methyl-5 : 5-cyclohexenylmethylbarbituric acid with dehydrocholic acid.
