合成路线1
该中间体在本合成路线中的序号:(II)Addition of cyanotrimethylsilane to 4'-iodoacetophenone (I) provided the O-silylated cyanohydrin (II), which was subsequently reduced to the amino alcohol (III) employing borane-dimethyl sulfide complex. Acylation of (III) with 2-propanesulfonyl chloride gave sulfonamide (IV). The hydroxyl group of (IV) was then fluorinated by means of diethylaminosulfur trifluoride, and the resultant racemic fluoride was resolved by chiral HPLC. Finally, Suzuki coupling of the required (S)-enantiomer (V) with boronic ester (VI) yielded the title biphenyl derivative.
