合成路线1
该中间体在本合成路线中的序号：(III)Methylation of (4-bromophenyl)acetonitrile (I) to afford 2-(4-bromophenyl)propionitrile (III) was carried out by heating with K2CO3 and dimethyl carbonate at 180 C in a sealed vessel. Alternatively, nitrile (III) was obtained by treatment of 4'-bromoacetophenone (II) with tosylmethyl isocyanide and potassium tert-butoxide. Nitrile (III) was reduced to amine (IV) using borane-dimethyl sulfide complex. Condensation of this amine with isopropylsulfonyl chloride furnished the corresponding sulfonamide (V). 4-Cyanophenylboronic acid (VII) was obtained by lithiation of 4-bromobenzonitrile (VI), followed by treatment with triisopropyl borate. Then, Suzuki coupling of boronic acid (VII) with bromide (V) furnished the title compound.
