Procedure
461 mg of 2-[1-(4-ethoxy-2,6-difluorobenzyl)-1,4,5,6-tetrahydrocyclopenta[c]-pyrazol-3-yl]-5-methoxy-N-(pyridin-4-yl)pyrimidin-4-amine 2-1-1 (0.964 mmol, 1.00 eq.) were dissolved in 42 mL of dry 1-methylpyrrolidin-2-one. 51 mg of potassium carbonate (0.366 mmol, 0.38 eq.) and 150 μL benzenethiol (1.45 mmol, 1.5 eq.) were added. The mixture was stirred for 1 h at 150° C. bath temperature. The reaction mixture was partitioned between aqueous half saturated ammonium chloride solution and DCM/isopropanol (4:1). The separated aqueous layer was extracted twice 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 349 mg (0.75 mmol, 78%) of analytically pure target compound.
