Reaction Steps

5-fluoro-2-(1-methyl-piperidin-4-yloxy)-phenylamine) (0.049 g, 0.22 mmol) was combined with 4-(2,6-difluoro-benzoylamino)-1H-pyrazole-3-carboxylic acid (0.053 g, 0.20 mmol), EDC (0.048 g, 0.25 mmol), HOBt (0.034 g, 0.25 mmol) and DMF (1 ml) and the resulting reaction mixture was stirred at ambient temperature for 18 hours. The reaction mixture was reduced in vacuo and purified by preparative LC/MS to give 4-(2,6-Difluoro-benzoylamino)-1H-pyrazole-3-carboxylic acid [5-fluoro-2-(1-methyl-piperidin-4-yloxy)-phenyl]-amide as a buff solid. (0.010 g, 11%) (LC/MS: Rt 2.19, [M+H]#474.27).
