실험 절차

2-(4-Aminophenyl)-5-(4-methoxyphenyl)-N-(2-thiazolyl)-imidazole-4-carboxamide (0.8 g) obtained in Example 48, sodium borohydride (0.13 g), 2.5N sulfuric acid (0.4 ml) and isopentyl aldehyde (0.3 ml) were treated in the same manner as in Example 72 to give 2-(4-isopentylaminophenyl)-5-(4-methoxyphenyl)-N-(2-thiazolyl)imidazole-4-carboxamide (0.3 g), melting point 235-239° C.
