実験手順
A mixture of 2-n-butyl-4-(2-aminoethyl)-1-[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methylimidazole hydrochloride (0.278 g), ethyl glyoxylate (0.179 g) and ethanol (5 ml) is refluxed for three days. To the mixture is added chloroform, and the mixture is washed, dried and evaporated to remove the solvent. The residue is purified by silica gel column chromatography (solvent; chloroform/methanol=10:1) to give ethyl 2-n-butyl-3-[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl-4,5,6,7-tetrahydroimidazo[4,5-c]pyridine-4-carboxylate (0.136 g) as a foam.
