该中间体在本合成路线中的序号:(VIII)Reaction of 3,5-dichlorobenzamide (V) with pivalaldehyde (VI) in the presence of benzotriazole (VII) gives rise to the benzotriazolyl benzamide (VIII). This is then condensed with the diamino cyclobutene (IV) to afford the racemic adduct (IX), which is finally resolved into the enantiomers employing chiral chromatography.
