Participants

Reaction Steps

In a reaction vial, propane-1-sulfonic acid [3-(5-amino-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluoro-phenyl]-amide (39, crude material e.g. from Scheme 5, step 2) is mixed with triethylamine (0.0363 mL, 0.26 mmol), 5-methyl-2,3-dihydro-isoxazole-3-carbonyl chloride (40, 45.4 mg, 0.312 mmol), 1 mL of tetrahydrofuran, and 1 mL of pyridine. The reaction is stirred at room temperature for 16 hours, then diluted with water, and extracted 3× with ethyl acetate. The combined organic layers are washed 2× with brine, dried with sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is further purified by reverse phase chromatography and the resulting material confirmed by LC-MS.
