Procedure
4-Chloro-7-nitro-benzo[b]thiophene-2-carboxylic acid methyl ester was prepared from 2,6-dichloro-3-nitro-benzoic acid using a procedure analogous to that described in Example 1 for 7-nitro-benzo[b]thiophene-2-carboxylic acid methyl ester. Then, following the procedure described in Example 1, the ester was hydrolyzed and the resulting acid coupled with N-(3-amino-5-tert-butyl-2-methoxy-phenyl)-methanesulfonamide to provide 4-chloro-7-nitro-benzo[b]thiophene-2-carboxylic acid (5-tert-butyl-3-methanesulfonylamino-2-methoxy-phenyl)-amide.
