A method for the isolation and purification of an imidazole compound, useful as an angiotensin II receptor inhibitor compound or as a key intermediate therefor, from a mixture of it with its regioisomer in a solvent by treament of the mixture with a strong acid to effect selective precipitation of the desired regioisomeric imidazole salt.

The identification of the AT1 and AT2 receptor subtypes has stimulated interest in developing balanced angiotensin II receptor antagonists. A series of 5-(3-amidopropanoyl)imidazoles has been prepared which possess balanced affinity for the AT1 and AT2 receptors. XR510 (1), 1-[[2'-[[(isopentoxycarbonyl)amino]sulfonyl]-3- fluoro(1,1'-biphenyl)-4-yl]methyl]-5-[3-(N-pyridin-3- ylbutanamido)propanoyl]
