Procedure

A solution of 500 mg of 4-bromo-2-methylbenzonitrile and 268 mg of sodium thiomethoxide in 3 mL of DMF was stirred for 1 h. The reaction mixture was diluted with ethyl acetate, washed with H2O, dried (MgSO4) and evaporated to afford 2-methyl-4-(methylthio)benzonitrile. 400 mg of 2-methyl-4-(methylthio)benzonitrile was reacted via Procedure T to give 2-methyl-4-(methylthio)benzoic acid. 430 mg of 2-methyl-4-(methylthio)benzoic acid was reacted via Procedure R to yield 2-methyl-4-(methylsulfonyl)benzoic acid. 60 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 2-methyl-4-(methylsulfonyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-yl)phenyl)-2-methyl-4-(methylsulfonyl)benzamide. MS (Q1) 401.0 (M)+.
