The title compound was obtained by a procedure similar to that in Step C of Example 9. Namely, (E)-5-(ethoxyimino-methyl)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-benzamide was reduced with borane-pyridine complex in the presence of dichloroacetic acid to give 5-(ethoxyamino-methyl)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-benzamide (97.7 mg, 80% in 2 steps).
