Procedure

(S)-4-((1-(5-Methyl-4-oxo-3-phenyl-3,4-dihydropyrrolo[2,1-f][1,2,4]triazin-2-yl)ethyl)amino)-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylic acid (30 mg, 0.07 mmol), benzylamine (20 mg, 0.19 mmol) and diisopropylethylamine (50 μl, 0.29 mmol) were dissolved in DMF (1.5 ml) and stirred for 30 min. The reaction flask was then sealed and T3P® (50% in DMF, 50 μl) was added dropwise and the reaction mixture was stirred overnight at room temperature. The mixture was poured into ice-water and extracted with ethyl acetate. The resulting organic solution was washed with water and brine, dried over magnesium sulphate, filtered and the solvents were removed under reduced pressure. The product was purified by flash chromatography (0% to 5% DCM/MeOH) to give 17 mg (46% yield) of the title compound as a white solid.
