Procedure

10% Palladium-on-carbon (10 mg) was added to a stirred solution of (E)-3-[3-{1-(1,3-benzodioxol-5-yl)-2-[(4-isopropylphenyl)sulfonamido]-2-oxoethyl}-1-methyl-1H-6-indolyl]-2-propenoic acid (the compound of Example 58, 80 mg, 0.14 mmol) and ammonium formate (64 mg, 0.5 mmol) in a 1:1 mixture of tetrahydrofuran and ethanol (10 ml total). The mixture was stirred at reflux for 48 h. cooled, filtered through Arbocel™ and concentrated. The grey foam was purified by flash column chromatography (elution with 98% dichloromethane/2% methanol) giving the product as a white foam.
