Procedure

in microwave tube was 5-chloro-7-(1-methyl-1H-pyrazol-3-ylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (80 mg, 0.29 mmol), N-(5-amino-2-methylphenyl)acetamide (48.0 mg, 0.29 mmol), and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (16.91 mg, 0.03 mmol) in DMA (0.5 mL).Pd2(dba)3 (13.38 mg, 0.01 mmol) and cesium carbonate (105 mg, 0.32 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 give offwhite solid. This solid was washed with 0.5 mL of EtOAc to give pure prod
