Reaction Steps
A solution of 0.4 g of (E)-3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]benzeneamine, 0.4 g of 5-methoxyhomophthalic anhydride, 50 ml of toluene and 10 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 ethanol to yield (E)-5-methoxy-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid, m.p. 190°-191° C.
