Preparation of aminomethyl-phenylimidazoles

摘要

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.
