実験手順

2-(4-Aminophenyl)-5-(4-methoxyphenyl)-N-(2-thiazolyl)-imidazole-4-carboxamide (1.0 g) obtained in Example 48, sodium borohydride (0.13 g), 4N sulfuric acid (0.2 ml) and butyraldehyde (0.3 ml) were treated in the same manner as in Example 72 to give 2-(4-butylaminophenyl)-5-(4-methoxyphenyl)-N-(2-thiazolyl)imidazole-4-carboxamide (1.1 g). This was converted to hydrochloride to give 2-(4-butylaminophenyl)-5-(4-methoxyphenyl)-N-(2-thiazolyl)-imidazole-4-carboxamide hydrochloride (0.20 g), melting point 250° C. or above.
