実験手順

A suspension of {4-[4-(5-Bromo-1H-indazol-3-yl)-[1,2,3]triazol-1-yl]-phenyl}-morpholin-4-yl-methanone (150 mg; 0.33 mmol; 1.0 eq.), 1-Methyl-1,2,3,6-tetrahydropyridine-4-boronic acid, pinacol ester (Boron Molecular, 221 mg; 0.99 mmol; 3.0 eq.), PdCl2(PPh3)2 (23 mg; 0.03 mmol; 0.10 eq.), cesium fluoride (151 mg; 0.99 mmol; 3.0 eq.) in dioxane (3 mL) and water (1.5 mL) was degassed with nitrogen flow and heat in MW at 150° C. for 10 min. The reaction mixture was filtered through a celite pad, water was added to the filtrate. Aqueous phase was extracted three time with DCM using separators tubes. Combined organic phases were concentrated under reduced pressure and the crude was purified by flash chromatography on silica (DCM/MeOH, gradient from 100:0 to 90:10) to give the title compound as a yellow powder. 1H NMR (300 MHz, DMSO) δ 13.36 (brs, 1H), 9.39 (s, 1H), 8.31 (s, 1H), 8.15 (d, J=8.0 Hz, 2H), 7.78-7.47 (m, 4H), 6.32-6.11 (m, 1H), 3.84-3.49 (m, 6H), 3.46-3.25 (m, 2H), 3.11-2.98 (m, 2H), 2.71-2.58 (m, 4H), 2.30 (s, 3H). HPLC (Condition A): Rt 2.22 min (purity 94.5%). MS (ESI+): 470.3, MS (ESI−): 468.3.
