Reaction Steps

25.0 mg of 2-[1-(2-fluorobenzyl)-1H-indazol-3-yl]-4-(pyridin-4-ylamino)pyrimidin-5-ol (3-3, 0.06 mmol, 1 eq.), 28.2 mg of 3-bromo-propane-1,2-diol (0.18 mmol, 3 eq.) and 41.9 mg of potassium carbonate (0.30 mmol, 5 eq.) were suspended in 466 μl of dry DMF. The reaction mixture was stirred at 100° C. oil bath temperature for 18 hours. Then the mixture was partitioned between half saturated aq. sodium chloride solution and ethyl acetate. The phases were separated and the aqueous layer was extracted once more with ethyl acetate and once with dichloromethane/isopropanol 4:1. The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by preparative thin layer chromatography to yield 2.60 mg (5.34 μmol, 9%) of the analytically pure target compound.
