실험 절차

To a solution of (6-chloroimidazo[1,2-b]pyridazin-3-yl)(1-methyl-1H-indazol-5-yl)methanone (410 mg, 1.32 mmol) in 10 mL THF was added methylmagnesium iodide (0.88 mL, 2.63 mmol) at 0° C. After stirring at 0° C. for 3 h, the reaction was quenched with saturated NH4Cl and concentrated under residue pressure. The residue was extracted with DCM three times. The organic layers were combined, dried over Na2SO4 and concentrated to give the title compound as a white solid (430.0 mg, 95%). 1H-NMR (400 MHz, DMSO-d6) δ ppm 8.17 (d, 1H), 7.99 (s, 1H), 7.50 (m, 1H), 7.40 (d, 1H), 7.25 (d, 1H), 5.98 (s, 1H), 3.99 (s, 3H), 2.05 (s, 3H). LCMS (method A): [MH]+=328, tR=4.55 min.
