合成路线1
该中间体在本合成路线中的序号：(XXI)The side-chain Fmoc protecting groups of (XX) were then cleaved by treatment with piperidine in DMF, and the resulting compound (XXI) was acetylated with acetic anhydride to give (XXII). Finally, removal of the remaining protecting groups and cleavage from the resin was achieved by treatment with liquid HF and anisole.
