Procedure

(S)-2-(1-Aminoethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (418 mg, 1.56 mmol) and benzyl 4-chloro-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate (500 mg, 1.74 mmol) were dissolved in tert-butanol (8 ml) and DIEA (2 ml, 11.45 mmol) was added. After stirring the mixture at 80° C. for 12 h, the solvent was evaporated under reduced pressure and the residue was suspended in water, basified with sodium carbonate and extracted with AcOEt (×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 50%, hexane-ethyl acetate) to obtain 560 mg (66% yield) of the title compound as a white solid. Purity 96%.
