Abstract

1,173,432. Propylenureas. BADISCHE ANALIN- & SODA-FABRIK A.G. 24 Aug., 1966 [25 Aug., 1965; 27 Aug., 1965], No. 37871/66. Heading C2C. Propylenureas having the general formula wherein the radicals R<SP>1</SP> to R<SP>7</SP> denote hydrogen atoms or identical or different linear or branched alkyl groups, are produced by reduction of a 2-oxohexahydropyrimidine having the general formula wherein R<SP>8</SP> denotes a hydrogen atom or an alkyl group, at a temperature from 0‹ to 200‹ C. with formic acid, or with hydrogen in the presence of a metal or metals having an atomic number of from 24 to 29 or copper chromite and a solvent. 2-Oxohexahydropyrimidine derivatives of the second general formula above are prepared by condensation of urea derivatives with suitable aldehydes, optionally in the presence of formaldehyde.
