Reaction Steps

The title compound was prepared by a procedure similar to that in Example 41. Namely, 5-(ethoxyamino-methyl)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-benzamide obtained in Example 17 was reacted with 4-oxo-4H-benzo[d][1,2,3]triazin-3-yl propionate prepared from propionic acid to give 5-[(ethoxy-propionyl-amino)-methyl]-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-benzamide (17.0 mg, 61%).
