合成路线:The esterification of 4-hydroxyphenylacetic acid (I) with isopropanol and H2SO4 gives the corresponding isopropyl ester (II),which is then cyclocondensed with 1-isobutoxy-2-chloroethyl isothiocyanate (III) by means of K2CO3 in acetone yielding isopropyl 2-[4-(4-isobutoxy-2-thiazolin-2-yloxy) phenyl]acetate (IV).Elimination of isobutanol from (IV) by means of p-toluenesulfonic acid in hot DMF affords isopropyl 2-[4-(2-thiazolyloxy)phenyl] acetate (V),which is methylated with methyl bromide and KOH in DMF giving isopropyl 2-[4-(2-thiazo)yloxy)phenyl]propionate (VI).Finally,this compound is hydrolyzed with NaOH in aqueous methanol.
