Participants

Reaction Steps

A mixture of 6-({3-(aminocarbonyl)-5-[2-fluoro-4-(1-hydroxy-1-methylethyl)phenyl]-2-thienyl}amino)pyridine-2-carboxylic acid (Table 3, Example 40) (50 mg, 0.12 mmol), 1-oxetan-2-ylmethanamine (11 mg, 0.12 mmol), 1-hydroxybenzotriazole hydrate (22 mg, 0.14 mmol), and PS-Carbodiimide (240 mg, 0.30 mmol, 1.25 mmol/g) in DMF (4 mL) was irradiated in a microwave at 100° C. for 10 minutes. Upon completion, the crude reaction was filtered, concentrated, and purified by silica gel chromatography (0-7% methanol/ethyl acetate) to afford the title compound.
