Abstract

264,804. Hoffmann- La Roche & Co., Akt.-Ges., F. Jan. 20, 1926, [Convention date]. Ureides of dialkyl- or arylalkyl-acetic acids are prepared by the prolonged heating of dialkyl- or axylalkyl-barbituric acids with dilute alkali solutions. The products possess hypnotic properties. According to the examples, (1) the ureide of allylisopropylacetic acid is obtained by heating allylisopropylbarbituric acid with dilute aqueous solutions of ammonia, ammonium carbonate, or sodium hydroxide to which sodium and potassium phosphates may be added, or with lime water saturated with carbon dioxide; (2) diallylacetylurea results when diallylbarbituric acid is boiled with weak aqueous ammonia; (3) phenylethylacetylurea is obtained by long heating of phenylethylbarbituric acid in slightly ammoniacal solution.
