Reaction Steps
A solution of 0.256 g of (E)-3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]benzeneamine and 0.148 g of 3-isochromanone was heated in a 126° C. oil bath for 17 hr. The residual materials were purified by silica gel chromatography using ethyl acetate-hexane (1:4 v/v) as the eluant to yield (E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzyl alcohol.
