반응 단계
A solution of 2.8 g of (E)-3-[2-[4-(cyclohexyl)-2-thiazolyl]ethenyl]benzeneamine, 1.78 g of homophthalic anhydride and 30 ml of toluene were heated to reflux for 0.5 hr. Cooling and filtration yielded 4.12 g of (E)-2-[2-[3-[2-[4-(cyclohexyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid; m.p. 210°-211° C. from tetrahydrofuran.
