合成路线1
该中间体在本合成路线中的序号：(XXVII)Methylation of the carbamate nitrogen atom of (XXIV) by means of iodomethane and NaH produced (XXV). Subsequent cleavage of the silyl ether group of (XXV) with HF gave diol (XXVI). The selective phosphitylation of the C-4 hydroxyl group of (XXVI), followed by oxidation of the resulting phosphite ester (XXVII) with m-chloroperbenzoic acid in the presence of Et3N, furnished phosphate (XXVIII). Finally, hydrogenolysis of the dibenzyl phosphate and benzyl carbamate functionalities of (XXVIII) provided the title compound, which was isolated as the hydrochloride salt.
