in microwave tube was 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (80 mg, 0.34 mmol), N-(3-aminophenyl)acetamide (51.4 mg, 0.34 mmol), and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (19.81 mg, 0.03 mmol) in DMA (0.5 mL).Pd2(dba)3 (15.68 mg, 0.02 mmol) and cesium carbonate (123 mg, 0.38 mmol) were added. degassed, filled with N2.capped. then microwave 150C for 30 min. added 2 mL of MeOH, filtered through celite. concentrated. The residue was purified by ISCO (Hex to Hex:EtOAc=1:4 to 1:1 to EtOAc), collected prod fractions. concentrated to brown semi-solid
