Abstract: 1,148,104. Hexahydropyrimidine derivatives. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 July, 1966 [25 May, 1966; 4 June, 1966; 15 June, 1966], No. 32820/66. Heading C2C. Novel hexahydropyrimidine derivatives of the formula where R 1 and R 2 denote hydrogen atoms or C 1-8 alkyl radicals, R 3 and R 4 denote C 1-4 alkyl radicals, R 5 denotes a hydrogen atom or a C 1-2 alkyl radical, R 6 denotes a C 1-6 alkyl radical or an alkoxyalkyl radical having one to four carbon atoms in the alkoxy group and one to six carbon atoms in the alkyl group, and X denotes an oxygen or sulphur atom, are prepared by reacting urea derivatives R 1 NH.CX.NHR 2 with aldehydes R 3 R 4 .CHCHO and R 5 .CHO or acetals thereof in a molar ratio of about 1: 1: 1 in the presence of an alkanol or a mono-C 1-4 alkyl ether of an α,#-alkanediol, at elevated temperature with an addition of an acid, the reaction product being neutralized with a base. The compounds may be converted to the corresponding 4-ureido-hexahydropyrimidines, which are useful as slow acting fertilizers, by reaction with urea.
