合成路线1
该中间体在本合成路线中的序号：(II)Reaction of 4-(trifluoromethyl)benzyl alcohol (I) with DSC followed by coupling with partially protected lysine (II) affords carbamate (III), which is converted into derivative (V) first by Boc removal with HCl/dioxane in dichloromethane followed by coupling with Boc-Gly-OH (IV) by means of EDCl and DIEA. Boc removal of compound (V) with HCl/dioxane in dichloromethane, followed by condensation with isophthaloyl dichloride (VI) by means of DIEA in DMF, gives compound (VII), which is finally subjected to methyl ester saponification with LiOH in THF/MeOH to provide the desired product.
