合成路线1
The esterification of 3-(4-hydroxyphenyl)propionic acid (I) with methanol and H2SO4 gives the corresponding methyl ester (II), which by condensation with epichlorohydrin (III) by means of K2CO3 in refluxing acetone affords methyl 3-[4-(2,3-epoxypropoxy)phenyl]propionate (IV). Finally, the epoxide ring is opened by reaction with isopropylamine (V) in refluxing methanol, and a final treatment with ethereal HCl is performed.
