الإجراء التجريبي

52 mg (0.14 mmol) of 6-chloro-N4-[3-fluoro-4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-phenyl]pyrimidine-2,4-diamine (from example 60) are dissolved in 2.5 ml of 2-ethylhexanol. 0.24 ml of N-ethyldiisopropylamine and 36 mg (0.42 mmol) of morpholine are added, and the mixture is heated at 150° C. bath temperature for 20 hours. After cooling, a little DMF is added and the mixture is chromatographed on silica gel 60 (gradient column: mobile phase: DCM:methanol=50:1, then 3:1). This gives an oil which is purified by preparative HPLC.
