合成路线1
该中间体在本合成路线中的序号：(IX)Lithiopyrimidine (X), prepared from 5-bromo-2-methylpyrimidine (IX) was added to phthalazine (XI) to produce adduct (XII). Displacement of ester (VIII) by dihydrophthalazine (XII) in the presence of butyllithium furnished the corresponding racemic amide. The desired (R)-enantiomer was finally isolated by chiral chromatography on a Chiralpak AD column.
