실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 3-(5-acetyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-yl-amino)-1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 209d (344 mg, 0.83 mmol), 4-chloro-2-{4,4-dimethyl-9-oxo-7-thia-10-azatricyclo[6.4.0.02,6]dodeca-1(8),2(6)-dien-10-yl}pyridine-3-carbaldehyde 109a (202 mg, 0.56 mmol), Pd(dppf)Cl2 (20 mg, 0.028 mmol), K3PO4 (235 mg, 1.11 mmol), sodium acetate (91 mg, 1.11 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 1 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. The mixture was cooled down to room temperature and filtered. The filtrate was concentrated under reduced pressure to afford 254a (400 mg, crude), which was directly used in next step without further purification. MS-ESI: [M+H]+ 612.3
