A solution of (Z)-5-chloro-N′-hydroxy-2-(1-methyl-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine-4-carboximidamide (Example 138B) (44 mg, 0.099 mmol), 1-hydroxycyclobutanecarboxylic acid (12.63 mg, 0.109 mmol), 1-hydroxybenzotriazole hydrate (7.57 mg, 0.049 mmol), and 4-methylmorpholine (0.038 mL, 0.346 mmol) in anhydrous dimethylformamide (1 mL) was treated with N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (28.4 mg, 0.148 mmol). The reaction was stirred for 3 hours at ambient temperature. The reaction was diluted with ethyl acetate and washed with water and brine. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated to provide the title compound. MS ESI(+) m/z 542.9 [M+H]+.
