실험 절차

100 mg of 2-[1-(4-ethoxy-2,6-difluorobenzyl)-1H-indazol-3-yl]-4-(pyridin-4-ylamino)pyrimidin-5-yl trifluoromethanesulfonate (1-7-2, 0.165 mmol, 1. eq.), 0.74 mg of palladium (II) acetate (0.003 mmol, 0.02 eq.) and 1.36 mg of propane-1,3-diylbis(diphenylphosphane) were dissolved in 1 ml of DMF under a nitrogen atmosphere. The mixture was heated to 60° C. bath temperature. Then 0.66 ml of triethylsilane (0.41 mmol, 2.5 eq.) were added. The resulting mixture was stirred at 60° C. bath temperature for 18 hours. Then the mixture was partitioned between saturated aq. sodium hydrogen carbonate solution and dichloromethane. The phases were separated and the aqueous layer was extracted twice with dichloromethane. The combined organic layers were washed with brine, dried over a silicone filter and concentrated in vacuo. Preparative HPLC purification provided 16 mg (0.03 mmol, 20.1%) of the analytically pure target compound.
