実験手順
A solution of 1.28 g of (E)-3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]benzeneamine, 0.81 g of homophthalic anhydride, 50 ml of toluene and 25 ml of tetrahydrofuran was heated to reflux for 0.5 hr. The solvents were removed by rotary evaporation and the residual materials were triturated with ethyl ether to yield 1.15 g of (E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid. Recrystallization from acetonitrile yielded 0.81 g of material; m.p. 204°-206° C. Anal. Calcd for C24H22N2O3S: C, 68.88; H, 5.30; N, 6.69. Found: C, 68.15; H, 5.21; N, 6.54.
