실험 절차

100 mg of 2-[1-(4-ethoxy-2,6-difluorobenzyl)-1,4,5,6-tetrahydrocyclopenta[c]-pyrazol-3-yl]-4-(pyridin-4-ylamino)pyrimidin-5-ol 2-2-1 (0.215 mmol, 1.00 eq.) were dissolved in 8 mL of dry DMF and 149 mg potassium carbonate (1.08 mmol, 5.00 eq.) and 47 mg 2-chloro-N,N-dimethylethanamine (0.323 mmol, 1.50 eq.) were added. The reaction mixture was stirred over night at 50° C. The reaction mixture was partitioned between aqueous half saturated sodium chloride solution and DCM/isopropanol (4:1). The separated aqueous layer was extracted with DCM/isopropanol (4:1). The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The purification of the residue by flash chromatography provided 51 mg (0.09 mmol, 42%) of analytically pure target compound.
