실험 절차

To a round bottom flask was added 6-(3-(2,4-difluorophenyl)-1-(pyrrolidin-3-yl)-1H-pyrazol-4-yl)-3-isopropyl-[1,2,4]triazolo[4,3-b]pyridazine (0.150 g, 0.366 mmol, Example #Q.1.1.1), DCM (10 mL), DIPEA (0.077 mL, 0.440 mmol) and acetyl chloride (0.029 mL, 0.403 mmol). The reaction mixture was stirred at ambient temperature for about 10 min. The reaction mixture was diluted with DCM (50 mL) and washed with saturated aqueous NaHCO3 (50 mL), dried with MgSO4, filtered and concentrated in vacuo. The crude material was purified by flash chromatography (40 g RediSep® silica gel; DCM/MeOH gradient from 1:0 to 9:1) to give the title compound (0.140 g, 84%): LC/MS (Table 1, Method g) Rt=2.07 min; MS m/z: 452.4 (M+H)+.
