(S)-2-(1-((5-(1H-Pyrazol-3-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 (50 mg, 0.07 mmol) and 1,1,1-trifluoro-2-iodoethane (36 mg, 0.17 mmol) were dissolved in DMF (2 ml) and cesium carbonate (140 mg, 0.43 mmol) was added. After stirring the mixture at 80° C. for 2 h, the solvent was evaporated under reduced pressure and the residue was suspended in water and extracted with ethyl acetate (×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 (54 mg) was treated with trifluoroacetic acid (1 mL, 13 mmol) and a solution of ammonia (7N in methanol, 10 ml, 70 mmol) according to the method described in Example 27 to give 4.6 mg (12% yield) of the title compound. Purity 93%.
