(S)-tert-Butyl (1-(5-bromo-4-oxo-3-phenyl-3,4-dihydropyrrolo[2,1-f][1,2,4]triazin-2-yl)ethyl)carbamate (1 g, 2.31 mmol) was dissolved in 25 mL anhydrous dioxane in a Schlenk vessel. Sodium iodide (1.38 g, 3.9 mmol), copper(I) iodide (0.13 g, 0.68 mmol) and trans-N,N′-dimethylcyclohexane-1,2-diamine (0.2 g, 1.41 mmol) were added under argon conditions and the mixture was further submitted to three vacuum-argon cycles. The reaction vessel was sealed and the mixture was heated at 120° C. for 7 h. The mixture was cooled to room temperature, diluted with ethyl acetate and filtered through celite. The organic phase was washed with 1N hydrochloric acid, water, brine and dried over sodium sulphate, filtered and evaporated under reduced pressure to obtain 1.43 g (88% yield) of the title compound as a oil. Purity 68%.
