반응 단계
A solution of 2.1 g of (E)-3-[2-[4-(cycloheptyl)-2-thiazolyl]ethenyl]benzeneamine, 1.25 g of homophthalic anhydride and 30 ml of toluene was heated to reflux for 0.5 hr. Cooling and filtration yielded 2.31 g of (E)-2-[2-[3-[2-[4-(cycloheptyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid; m.p. 189°-190° C. from tetrahydrofuran.
