실험 절차

120 mg of 2-[1-(4-ethoxy-2,6-difluorobenzyl)-1H-indazol-3-yl]-N-(pyridin-4-yl)-pyrimidin-4-amine (5-1-1, 0.262 mmol, 1. eq.) were suspended in 12 ml of dry DMF. 426 mg of cesium carbonate (1.31 mmol, 5 eq.) and 142 mg of 1,3,2-dioxathiolane 2-oxide (1.31 mmol, 5 eq.) were added under nitrogen atmosphere. The reaction mixture was stirred at 60° C. bath temperature for 18 hours. 142 mg of 1,3,2-dioxathiolane 2-oxide (1.31 mmol, 5 eq.) were added and the mixture was stirred at 60° C. bath temperature for further 22 hours. Then the mixture was partitioned between water and dichloromethane/isopropanol 4:1. The phases were separated and the aqueous layer was extracted twice with dichloromethane/isopropanol 4:1. The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by flash chromatography and preparative TLC to yield 14.2 mg (0.03 mmol, 10.5%) of the analytically pure target compound.
