実験手順
To a solution of 4-{4-[6-amino-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-3-yl]-pyrazol-1-yl}-piperidine-1-carboxylic acid tert-butyl ester (BB3) (370 mg, 0.67 mmol), trifluoromethanesulfonic acid 5-bromo-8-fluoroisoquinolin-3-yl ester (250 mg, 0.67 mmol), and Pd(PPh3)4 (40 mg, 0.03 mmol) in 1,4-dioxane (8.0 mL) in a sealable microwave tube was added a solution of Cs2CO3 (440 mg, 1.3 mmol) in H2O (2 mL). The tube was sealed, evacuated and refilled with nitrogen (3×), and heated in the microwave reactor to 100° C. for 30 minutes. The reaction mixture was diluted with EtOAc, washed with water and brine, dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified by chromatography on silica gel, eluting with 5% 7M NH3 in MeOH and DCM. One obtained the title compound as a yellow solid. 1H NMR (400 MHz, CDCl3): δ=1.24-1.35 (m, 4H), 1.49 (s, 9H), 1.93-2.06 (m, 2H), 2.19 (d, J=2.3 Hz, 1H), 2.86-2.96 (m, 1H), 6.55 (br. s., 2H), 7.17 (dd, J=9.4, 8.3 Hz, 1H), 7.68 (s, 1H), 7.80 (s, 1H), 7.95 (dd, J=8.3, 4.8 Hz, 1H), 8.00 (d, J=2.3 Hz, 1H), 8.31 (s, 1H), 8.32 (d, J=2.3 Hz, 1H), 9.57 (s, 1H). MS (ES+): m/z=566.87/567.69 [MH+]. HPLC: tR=3.08 min (ZQ2, polar—5 min).
