Abstract
C : C-Phenylethyl-N-n-propyl-barbituric acid is prepared by the catalytic hydrogenation of C : C-phenylethyl-N-allyl-barbituric acid, which may be prepared by the process described in Specification 391,741. The product possesses therapeutic properties. Examples are given of the hydrogenation (1) in methyl alcohol solution at ordinary pressure and temperature in the presence of palladium chloride, and (2) in ethyl alcohol solution using a nickel catalyst and heating in an autoclave.ALSO:C : C-Phenylethyl-N-n-propyl-barbituric acid is prepared by the catalytic hydrogenation of C : C-phenylethyl-N-allyl-barbituric acid.
