Abstract

Aminomethyl-phenylimidazoles are produced by reaction of an ester of a hydroxymethyl-phenylimidazole with an amine. A particularly preferred ester is the acetate ester. The aminomethyl-phenylimidazoles have useful properties as highly selective partial agonists or antagonists at brain dopamine receptor subtypes. A preferred compound prepared is 5-fluoro-2-4-(2-phenyl-1H-imidazol-5-yl)methyl!-1-piperazinyl!pyrimidine . Esters of the hydroxymethyl-phenylimidazoles are useful intermediates.
