Procedure

200 μL of 1-(2-bromoethyl)-1H-pyrrole and 556 mg of Cesium Carbonate were added to 150 mg of methyl 2-chloro-4-(methylsulfonamido)benzoate in DMF and stirred at room temperature for 16 hours. The reaction mixture was extracted in Ethyl Acetate twice with saturated bicarbonate and once with brine, dried over Magnesium Sulfate, filtered and concentrated to give methyl 4-(N-(2-(1H-pyrrol-1-yl)ethyl)methylsulfonamido)-2-chlorobenzoate. 230 mg of methyl 4-(N-(2-(1H-pyrrol-1-yl)ethyl)methylsulfonamido)-2-chlorobenzoate was hydrolyzed via Procedure M to yield 221 mg of crude 4-(N-(2-(1H-pyrrol-1-yl)ethyl)methylsulfonamido)-2-chlorobenzoic acid.
