Procedure

(S)-2-(1-((5-(1H-Pyrazol-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (43 mg, 0.07 mmol) and 2-chloro-N,N-dimethylethanamine chlorhydrate (43 mg, 0.30 mmol) were dissolved in DMF (3 ml) and cesium carbonate (240 mg, 0.74 mmol) was added. After stirring the mixture at 75° C. for 3.5 h, the solvent was evaporated under reduced pressure and the residue was suspended in water and extracted with dichloromethane (×3). The organic phase was successively washed with water and brine, dried over magnesium sulphate, filtered and the solvent evaporated under reduced pressure. The residue was purified using SP1® Purification System (0% to 3%, dichloromethane-methanol) to obtain 31 mg (57% yield) of the title compound as a brown solid. Purity 90%.
