The deprotection of the carbamate (XVIII) by means of TFA gives the free aminoester (XIX), which is reprotected with Fmoc-Cl and NaHCO3 yielding the acid (XX). The esterification of the hydroxy group of he intermediate (XVII) with the acid group of (XX) by means of EDC affords the expected ester (XXI). The oxidation of the methylsulfanyl group of (XXI) with oxone affords the corresponding methylsulfonylmethyl ester (XXII), which is cyclized by means of piperidine in DMF to give the macrocyclic epoxide (XXIII). Finally, this compound is treated with 12 N HCl in dimethoxyethane/water.
