반응 단계
A solution of 2.7 g of (E)-3-[2-[4-(cyclopentyl)-2-thiazolyl]ethenyl]benzeneamine, 1.78 g of homophthalic anhydride and 40 ml of toluene was heated to reflux for 0.5 hr. Cooling and filtration yielded 3.75 g of (E)-2-[2-[3-[2-[4-(cyclopentyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid; m.p. 209°-210° C. from tetrahydrofuran.
