In a manner analogous to Example 7a and 7b, when 2-(1-carboxycyclopentyl)benzoic acid methyl ester is reacted with (E)-3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]benzeneamine, there is obtained (E)-2-[1-[[[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenyl]amino]carbonyl]cyclopentyl]benzoic acid methyl ester which is converted to (E)-2-[1-[[[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenyl]amino]carbonyl]cyclopentyl]benzoic acid.
