実験手順
2.2 g of methyl 4-(methylsulfonyl)-2-nitrobenzoate was reacted via Procedure C to afford methyl 2-amino-4-(methylsulfonyl)benzoate. 500 mg of methyl 2-amino-4-(methylsulfonyl)benzoate was hydrolyzed via Procedure M to give 2-amino-4-(methylsulfonyl)benzoic acid. 100 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 2-amino-4-(methylsulfonyl)benzoic acid via Procedure G. The product was purified on reverse phase HPLC to yield 2-amino-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(methylsulfonyl)benzamide. MS (Q1) 402.0 (M)+.
