Reaction Steps

To a stirring solution of 4-chloro-N-(2,5-dichlorophenyl)-N-(3-(2-carboxymethyl-3-thiazolidinyl)-1(R)-methylpropyl)benzenesulfonamide (109 mg, 0.203 mmol) in methanol (20 mL) was added 50% aqueous KOH (1.0 mL) and the mixture was stirred at room temperature for 18 hours. The solvent was removed and the crude mixture was dissolved in CH2Cl2 and washed with 1N HCl. The CH2Cl2 layer was dried over Na2SO4 and evaporated to give crude product. Purification was performed over silica gel using 5-10% methanol in CH2Cl2 with 0.5% NH4OH to afford 4-chloro-N-(2,5-dichlorophenyl)-N-(3-(2-carboxy-3-thiazolidinyl)-1(R)-methylpropyl)benzenesulfonamide as a beige foam in 66% yield. IR (KBr) 1467, 1351, 1167, 1094, 753, 622 cm−1; MS (ESI+), 523 (M+H)+.
