実験手順

Utilizing the procedure described in Example 1(a) employing 5-(4-chlorobutyl)-1-cyclohexyl-1H-tetrazole in lieu of ethyl 4-bromomethylbenzoate and imidazo[4,5-b]pyridine in lieu of . imidazo[4,5-c]pyridine 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 which was recrystallized from diethyl ether-chloroform to yield 3-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butyl]-3H-imidazo [4,5-b]pyridine as a colorless crystalline solid, having a melting point of 94°-95° C. and the following physical characteristics:
