実験手順

54 mg of 4-({2-[1-(2-fluorobenzyl)-1H-indazol-3-yl]-5-methoxypyrimidin-4-yl}amino)pyridine-3-carbonitrile (24-1, 0.12 mmol, 1. eq.) were dissolved in 1.6 ml of dimethyl sulfoxide under nitrogene atmosphere. 42 μl of 3 M aqueous sodium hydroxide solution (0.126 mmol, 1.05 eq.) were added. The mixture was oilbath heated to 63° C. bath temperature. At this temperature 302 μl hydrogen peroxide (30% in water) (9.87 mmol, 82.2 eq.) were added dropwise. The reaction mixture was stirred at 65° C. bath temperature for 3 hours and at room temperature for 24 hours. After stirring the mixture one hour with ice-water it was extracted three times with dichloromethane/isopropanol 4:1. The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by preparative TLC (dichloromethane/methanol 9:1) to yield 12.0 mg (0.02 mmol, 20.5%) of the analytically pure target compound.
