실험 절차

To a mixture of tert-butyl 4-(6-bromopyridin-2-yl)-6-methoxy-6-methyl-1,4-diazepane-1-carboxylate (530 mg, 1.33 mmol) and 6-chloro-1H-pyrazolo[4,3-c]pyridine (203 mg, 1.33 mmol) in 1,4-dioxane (30 mL) was added CuI (101 mg, 0.53 mmol), N1,N2-dimethylethane-1,2-diamine (94 mg, 1.06 mmol), and K2CO3 (734 mg, 5.32 mmol). The mixture was heated at 100° C., which was monitored by LCMS. After completion of the reaction, it was concentrated under reduced pressure. The crude material was purified by silica gel chromatography using petroleum ether:EtOAc (3:1˜1:1) as eluting solvents to afford tert-butyl 4-(6-(6-chloro-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-6-methoxy-6-methyl-1,4-diazepane-1-carboxylate as yellow solid (446 mg, 71%). MS (ESI) m/z: 473 [M+H]+.
