実験手順

A sealed tube equipped with a magnetic stirrer was charged with 138c (150 mg, 0.40 mmol), 3-(acetoxymethyl)-2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)pyridin-4-ylboronic acid 116c (495.6 mg, 1.2 mmol), Pd2(dba)3 (36.6 mg, 0.040 mmol), P(cy)3(44.6 mg, 0.16 mmol), Cs2CO3 (391.2 mg, 1.2 mmol), dioxane (8 mL), and water (0.2 mL). After three cycles of vacuum/argon flush, the mixture was heated at 120° C. for 4 h. After this time the reaction was cooled to room temperature. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 40:1 ethyl acetate/methanol and further purified by reverse-phase prep-HPLC to afford 138 (48 mg, 18%) as a yellow solid. MS-ESI: [M+H]+ 667.3. 1H NMR (500 MHz, DMSO-d6) δ 12.05 (s, 1H), 8.65 (d, J=2.0 Hz, 1H), 8.57 (d, J=5.0 Hz, 1H), 8.55 (d, J=3.0 Hz, 1H), 8.44 (s, 1H), 7.91 (d, J=2.0 Hz, 1H), 7.87 (d, J=2.5 Hz, 1H), 7.79 (dd, J=1.0 Hz, 13.0 Hz, 1H), 7.54 (d, J=5.0 Hz, 1H), 7.39 (dd, J=2.5 Hz, 9.0 Hz, 1H), 7.26-7.23 (m, 2H), 4.97-4.95 (m, 1H), 4.58-4.54 (m, 2H), 4.48-4.46 (m, 1H), 4.43-4.41 (m, 1H), 4.38-4.37 (m, 2H), 3.69-3.68 (m, 1H), 3.41-3.39 (m, 1H), 3.11-3.09 (m, 1H), 2.97-2.93 (m, 1H), 2.56-2.54 (m, 1H), 2.35-2.32 (m, 2H), 2.21-2.17 (m, 1H), 1.40 (s, 9H), 0.94 (d, J=6.5 Hz, 3H),
