Procedure
Add DBU (0.29 mL, 1.92 mmol) to 3-[4-(2-amino-phenoxy)-phenyl]-4-cyano-5-ethyl-1-methyl-1H-pyrrole-2-carboxylic acid ethyl ester (0.25 g, 0.64 mmol, prepared in example E-95) in methylene chloride at room temperature with stirring. After 10 minutes, cool to 0° C. and add isopropyl-sulfonylchloride (0.11 mL, 0.96 mmol). Stir the reaction mixture at 0° C. for 30 minutes and then at room temperature for 2-6 hours. Then pour the reaction mixture into water and extract with methylene chloride. Combine the organic extracts, wash with 1N HCl, water and brine, dry over anhydrous magnesium sulfate, filter, and concentrate under reduced pressure. Purify the residue by flash chromatography eluting with acetonitrile:methylene chloride to provide the title compound.
