Reaction Conditions

Reaction Steps

mCPBA (57-86%, 15 mg) was added to a solution of 6-{5-[(cyclopropylamino)carbonyl]-3-fluoro-2-methylphenyl}-N-(1,1-dimethylethyl)-3-pyridinecarboxamide (Intermediate 9, 20 mg) in chloroform (3 ml) at 60° C. and the reaction maintained at 60° C. for 7 hrs. The reaction was allowed to cool, diluted with methanol, and passed through an aminopropyl SPE (2 g) and an SCX SPE (1.0 g). The filtrate was reduced to dryness under vacuum and the residue triturated with ether to give 6-{5-[(cyclopropylamino)carbonyl]-3-fluoro-2-methylphenyl}-N-(1,1-dimethylethyl)-3-pyridinecarboxamide 1-oxide as a white solid.
