Procedure
[4,5-Dibromo-3-(3-cyano-5-difluoromethyl-phenoxy)-2-fluoro-phenyl]-acetic acid ethyl ester (200) was isolated as a byproduct in the Sandmeyer reaction used in the preparation of 186 described in step 1 of example 40. The dibromo compound was converted to I-104 by the procedure described in steps 7 to 9 of example 1 except in the present example, 4-amino-3-methyl-benzenesulfonamide replaced 4-amino-benzenesulfonamide.
