Utilizing the procedure described in Example 5(b) employing a mixture of 7-(3H-imidazo[4,5-c]pyridin-3-yl)heptanoic acid and 7-(1H-imidazo[4,5-c]pyridin-1-yl)heptanoic acid, potassium salts in lieu of 4-(1H-imidazo[4,5-c]pyridin-1-ylmethyl) benzoic acid, potassium salt yielded an impure mixture of isomers. The mixture was purified by column chromatography (silica gel, 5% ethanol in chloroform) to yield a less polar isomer N-cyclohexyl-N-methyl-7-(3H-imidazo[4,5-c]pyridin-3-yl)heptanamide as a pale-yellow oil, having the following physical characteristics:
