Reaction Steps

310 mg of 2-[5-cyclopropyl-1-(4-ethoxy-2,6-difluorobenzyl)-4-methyl-1H-pyrazol-3-yl]-5-methoxy-N-(pyridin-4-yl)pyrimidin-4-amine 2-1-12 (0.629 mmol, 1 eq.) were dissolved in 27.2 mL of dry 1-methylpyrrolidin-2-one. 348 mg of potassium carbonate (2.52 mmol, 4.0 eq.), molecular sieve and 97 μL benzenethiol (0.944 mmol, 1.5 eq.) were added. The mixture was stirred for 1 hour at 150° C. bath temperature. 348 mg of potassium carbonate (2.52 mmol, 4.0 eq.) and 97 μL benzenethiol (0.944 mmol, 1.5 eq.) were added again and the mixture was stirred for a further hour at 150° C. bath temperature. Then the reaction mixture was partitioned between aqueous half saturated ammonium chloride solution and ethyl acetate. The separated aqueous layer was extracted twice with ethyl acetate. The combined organic layers were dried over a silicone filter and concentrated in vacuo. The purification of the residue by flash chromatography provided 191 mg (0.36 mmol, 56%) of analytically pure target compound.
