该中间体在本合成路线中的序号：(VIII)The compound has also been obtained by solid phase synthesis. Attachment of (S)-3-hydroxypyrrolidine (VII) to p-nitrophenylcarbonate Wang resin (VI) in the presence of diisopropylethylamine provided the resin bound pyrrolidinol (VIII). Coupling of (VIII) with 3-bromo-2-chloro-5-hydroxypyridine (II) under Mitsunobu conditions gave resin (IX). Further Suzuki coupling of (IX) with 4-cyanophenylboronic acid (IV) afforded (X). The title compound was then cleaved from the resin (X) by treatment with trifluoroacetic acid.
