Alternatively, after coupling of the peptide resin (XIII) with alpha-Boc-L-4-(Fmoc-amino)phenylalanine (XIV), the Fmoc protecting group was not removed, yielding resin (XXVI). Subsequent coupling cycles with amino acids (XVIII), (XX), (XXII) and (XXIV) as above finally produced resin (XXVII). The Fmoc group was then deprotected by treatment with piperidine, and the resulting aniline was acylated with L-hydroorotic acid (XVI) to provide resin (XXVIII), which was finally cleaved and deprotected by treatment with HF.
