Twenty one derivatives of 2,3-dihydroimidazo[1,2-a]pyrimidine-6-carboxylic acid (6 n-butyl amides and 15 free acids) bearing the aromatic ring in position 1 or 2 were obtained. They were synthesized by aminolysis or hydrolysis of respective ethyl esters. Pharmacological studies on the central action of eight compounds 1, 2, 4, 5, 7, 8, 9 and 10 were carried out on mice and rats. The most active compounds, producing sedation and hypothermia, and 1, 2 and 5. The compounds decreased amphetamine-induced hyperactivity. Besides, compound 2 exerted analgesic effect in mice.
