Procedimiento

In a 40mL vial (t=g) was 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (50 mg, 0.21 mmol), [Reactants], and cesium carbonate (77 mg, 0.24 mmol) in DMA (0.5 mL) ([VOLUME]),Pd2(dba)3 (9.80 mg, 10.70 µmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (12.38 mg, 0.02 mmol) were added. to give a brown suspension. The vial was filled with N2, 150C microwave for 30 min. LCMS showed completion. added MeOH (3 mL), filtered through celite. concentrated. The residue was purified by ISCO (Hexane to EtOAc:Hex=1;1 to EtOAc) to give about 34 mg offwhite solid
