该中间体在本合成路线中的序号：(XLVII)

The condensation of tetrapeptide (XLVI) with tripeptide alcohol (XXXVIII) under modified Mitsunobu conditions furnished the linear heptadepsipeptide (XLVII). Removal of both Boc group and tert-butyl ester was accomplished by treatment with TFA at r.t. Finally, cyclization to the target compound was performed either with EDC and HOAt or with HATU and collidine.
