実験手順

4-(1-(4-Methoxybenzyl)-3-(1-methyl-1H-imidazol-5-yl)-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorobenzenamine (0.213 g, 0.479 mmol), 2-(4-fluorophenyl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid (0.561 g, 2.40 mmol, prepared in Example 19, step C), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.459 g, 2.40 mmol), 1H-benzo[d][1,2,3]triazol-1-ol hydrate (0.367 g, 2.40 mmol), N-ethyl-N-isopropylpropan-2-amine (0.310 g, 2.40 mmol) and CH2Cl2 (5 mL) were charged in a 50 mL single-neck, round-bottomed flask. The reaction mixture was stirred at room temperature until LC-MS shows that the starting material had been consumed (overnight). Then the reaction was partitioned between EtOAc (50 mL) and water (50 mL). The phases were separated and the aqueous phase was extracted with EtOAc (3×50 mL). The combined organic layers were dried (Na2SO4), filtered and concentrated to yield a crude product. The crude product was purified by silica gel chromatography (CH2Cl2/MeOH from 100/1 to 50/1, v/v) to afford product (0.201 g, 63.5%). LRMS (APCI pos): >95% purity, 254 nm, m/e 661 (M+1). 1H NMR (400 MHz, CDCl3 δ 11.75 (s, 1H), 8.31 (d, 1H), 8.25 (d, 1H), 8.14 (d, 1H), 7.87 (dd, 1H), 7.60 (s, 1H), 7.52 (m, 2H), 7.42 (s, 1H), 7.28 (m, 3H), 7.13 (m, 3H), 6.75 (m, 2H), 6.20 (d, 1H), 5.56 (s, 2H), 3.83 (s, 3H), 3.67 (s, 3H).
