in microwave tube was 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (100mg, 0.43 mmol), [Reactants], and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (24.76 mg, 0.04 mmol) in DMA (1.0 mL).Pd2(dba)3 (19.60 mg, 0.02 mmol) and cesium carbonate (279 mg, 0.86 mmol) were added. degassed, filled with N2.capped. then microwave 150C for 30 min. filtered, then concentrated. The crude material was purified by ISC(Hex to Hex:EtOAc=1;1 to EtOAc to EtOAc:MeOH=10:1 to EtOAc:MeOH:Et3N=10:1:0.1)) to give no very pure product. collect the product fraction, concentrated to dryness. no pure enough, tried to form solid. it failed sent to ananlytic group for purification. came back. it was OK 1TFA salt. NMR LCMS are OK
