Versuchsvorschrift

5-chloro-7-(cyclobutylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (80 mg, 0.32 mmol), N-(5-amino-4-fluoro-2-methylphenyl)acetamide (58.8 mg, 0.32 mmol), and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (18.69 mg, 0.03 mmol) in DMA (5 mL) were added to a microwave tube. Pd2(dba)3 (14.79 mg, 0.02 mmol) and cesium carbonate (210 mg, 0.65 mmol) were added. The solution was degassed, filled with N2, capped, then microwaved at 150C for 30 min. The organic solvent was removed. TLC showed two closely associated peaks, so product was purified via Gilson. Appropriate fractions were collected, concentrated by rotovap, and dried in the oven overnight. LCMS, HPLC, and NMR revealed desired product. See attachments.
