Versuchsvorschrift
250 mg of 4-(2-bromoethylsulfonyl)benzonitrile was used in Procedure P with pyrazole to yield 4-(2-(1H-pyrazole-1-yl)ethylsulfonyl)benzonitrile. 300 mg of 4-(2-(1H-pyrazole-1-yl)ethylsulfonyl)benzonitrile was reacted via Procedure T to give 4-(2-(1H-pyrazole-1-yl)ethylsulfonyl)benzoic acid. 75 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 4-(2-(1H-pyrazole-1-yl)ethylsulfonyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield 4-(2-(1H-pyrazol-1-yl)ethylsulfonyl)-K-(4-chloro-3-(pyridin-2-yl)phenyl)benzamide. MS (Q1) 467.0 (M)+.
