Prepare the title compound in the manner analogous to the procedure set fourth in example E-222 using 4-cyano-5-ethyl-1-methyl-3-(4-trifluoromethanesulfonyloxyphenyl)-1H-pyrrole-2-carboxylic acid ethyl ester (prepared in example E-97a or 97b) and 4-bromo-indole. Purify the material by silica gel chromatography eluting with eluting with hexanes/ethyl acetate 4:1 to provide the title compound which is triturated with methylene chloride and hexanes to provide the title compound as a white solid. Mass spectrum (m/e): 398.2 (M*+1).
