Reaction Steps
1.2 g of 4-(2-chloroethyl)morpholine and 2.5 g of Cesium Carbonate were added to 334 mg of methyl 2-chloro-4-(methylsulfonamido)benzoate in 7 mL of DMF and stirred in the microwave at 150° C. for 30 minutes. The reaction mixture was extracted in Ethyl Acetate twice with water, dried over Magnesium Sulfate, filtered, concentrated to give crude methyl 2-chloro-4-(N-(2-morpholinoethyl)methylsulfonamido)benzoate. 476 mg of methyl 2-chloro-4-(N-(2-morpholinoethyl)methylsulfonamido)benzoate was hydrolyzed via Procedure M and purified by reverse phase HPLC to yield 460 mg of crude 2-chloro-4-(N-(2-morpholinoethyl)methylsulfonamido)benzoic acid. 100 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 2-chloro-4-(N-(2-morpholinoethyl)methylsulfonamido)benzoic acid via Procedure G. The crude product was purified by reverse phase HPLC to yield 2-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(N-(2-morpholinoethyl)methylsulfonamido)benzamide. MS (Q1) 549 (M)+.
