Vorschrift

Using 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-5, formyl-N-(2-hydroxy-ethoxy)-benzamide obtained in Step F of Example 1 as a starting material, and 2-methyl-propane-1,2-diol obtained in Step A instead of ethylene glycol used as a reagent in Step G of Example 1, synthesis similar to that in Step G of Example 1 was performed. The resultant cyclic acetal was subjected to reduction condition similar to that in Step H of Example 1 to give the title compound.
