実験手順
600 mg (2.47 mmol) of 5-(4-amino-2-fluorophenoxy)-1H-indazole (from example XII) are suspended in 100 ml of water. 510 mg (2.47 mmol) of 4-chloro-6-(4-pyridinyl)-2-pyrimidineamine (from example XXIX) and 0.25 ml of concentrated aqueous hydrogen chloride solution are added, and the mixture is stirred at 100° C. overnight. For work-up, the reaction solution was made alkaline with saturated sodium bicarbonate solution and extracted 3× with ethyl acetate. The precipitate obtained contains crude product and is filtered off with suction. The organic phase is dried with sodium sulfate and concentrated using a rotary evaporator. The residue is combined with the precipitate and purified by preparative HPLC.
