반응 단계
In a 40mL vial (t=g) was 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (88 mg, 0.38 mmol), [Reactants], and cesium carbonate (135 mg, 0.41 mmol) in DMA (0.5 mL) ([VOLUME]),Pd2(dba)3 (17.24 mg, 0.02 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (21.79 mg, 0.04 mmol) were added. to give a brown suspension. The vial was filled with N2, 150C microwave for 30 min. LCMS showed completion. added DMF(3 mL), filtered through celite. concentrated. The residue was washed with EtOAc and water, MeoH to give about 55mg light brown solid
