Procedure

In a round bottom flask, 4-methyl-7H-pyrrolo[2,3-d]pyrimidine (7, 97.0 mg, 0.728 mmol) is combined with 2-methyl-propane-1-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (62, 202 mg, 0.728 mmol), potassium hydroxide (204 mg, 3.64 mmol) and 1.4 mL of methanol. The reaction is stirred at room temperature for 7 hours. The reaction is neutralized with 0.1 N aqueous hydrochloric acid and extracted 3× with ethyl acetate. The combined organic layer is washed with brine, dried with sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is purified by silica gel column chromatography, eluting with ethyl acetate and dichloromethane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound (77, 113 mg). MS (ESI) [M−H+]−=409.2.
