Procedure
By the method of Example 1, Step H, 2-chlorobenzoic acid is converted to its imidazolide and reacted with 3-n-butyl-4-[(3-fluoro-2'-sulfamoylbiphenyl-4-yl)methyl]-1-[5-nitro-2-(trifluoromethyl)phenyl]-1H-pyrazole-5-carbonitrile (from Step B) in the presence of DBU to give the title compound.
