Procedure

The title compound was prepared by a procedure similar to that in Example 41. Namely, 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-(methoxyamino-methyl)-benzamide obtained in Example 15 was reacted with 4-oxo-4H-benzo[d][1,2,3]triazin-3-yl isobutyrate prepared from isobutyric acid to give 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-[(isobutyryl-methoxy-amino)-methyl]-benzamide (88.9 mg, 77%).
