Procedure
(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 (38 mg, 0.07 mmol) and 2-bromoethanol (15 mg, 0.12 mmol) were dissolved in DMF (1.5 ml) and cesium carbonate (102 mg, 0.31 mmol) was added. After stirring the mixture at 75° C. for 2 h, the solvent was evaporated under reduced pressure and the residue was suspended in water, basified with sodium carbonate 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 (31 mg, 96% purity) was used in the next synthetic step without further purification.
