실험 절차

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 271a (650 mg, 1.50 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (1.79 g, 4.5 mmol), Pd2(dba)3 (137.2 mg, 0.15 mmol), P(cy)3(167.4 mg, 0.60 mmol), Cs2CO3 (978 mg, 3.0 mmol), dioxane (20 mL), and water (0.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 110° C. for 16 h. After this time the reaction was cooled to room temperature. Lithium hydroxide monohydrate (1.89 g, 45 mmol) and water (2.0 mL) were added. The resulting mixture was stirred at 45° C. for 4 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 3:1 ethyl acetate/petroleum ether to afford 271b (290 mg, 27%) as a yellow solid. MS-ESI: [M+H]+ 709.3
