| abstract |
The invention relates to a process for the preparation of imidazole (1,2-a) pyrimidines for use as medicaments. The aim of the invention is to provide novel compounds with valuable pharmacological properties, in particular anxiolytic effect. According to the invention, compounds of the formula (1) are prepared in which, for example: R is a straight-chain C 1-8-alkyl group, a straight-chain C 2-8-alkenyl radical, etc.; R deep 1 and R deep 2 - equal to or different from each other - a hydrogen atom, a straight-chain C 1-8-alkyl group, a C 2-5 alkenyl lower group, a cycloalkyl group, among others; R deep 3 is a C 1-5 lower alkyl group; X is an oxygen or sulfur atom; and their acid addition salts. |
