Versuchsvorschrift

To 4-methyl-7H-pyrrolo[2,3-d]pyrimidine (42, 0.192 g, 1.44 mmol), propane-1-sulfonic acid (2,4-difluoro-3-formyl-phenyl)-amide (9, 0.456 g, 1.73 mmol), potassium hydroxide (0.263 g, 4.69 mmol) and 1.0 mL of methanol were added to provide a solution. The reaction was allowed to stir at room temperature for 30 hours, then quenched with water and adjusted to pH ˜5 with acetic acid and sodium bicarbonate and extracted with ethyl acetate and saturated sodium chloride. The organic layer was washed with water and brine, dried with magnesium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with ethyl acetate and hexane with 4% acetic acid. Appropriate fractions were combined and concentrated under vacuum to provide the desired compound as an off-white solid (P-0055, 215 mg). 1H-NMR(dmso-d6) showed it contains about >80% of the desired compound, used in the next step without further purification. MS(ESI) [M+H−]+=397.1.
