Reaction Steps

In a reactor vessel (S)-2-(1-amino-3-(benzyloxy)propyl)-3-(3,5-difluorophenyl)-4-oxo-3,4-dihydropyrrolo[2,1-f][1,2,4]triazine-5-carbonitrile (42 mg, 0.1 mmol) and 4-amino-6-chloropyrimidine-5-carbonitrile (16 mg, 0.1 mmol) were dissolved in 1-butanol (840 μl) under argon atmosphere. N,N-Diisopropylethylamine (76 μl, 0.87 mmol) was added and the reaction mixture was heated at 120° C. overnight. Further N,N-diisopropylethylamine (76 μl, 0.87 mmol) was added afterwards and the reaction mixture was stirred at 120° C. overnight. The crude was evaporated and purified using SP1® Purification System (0% to 100%, hexane-ethyl acetate) to obtain 34 mg (64% yield) of the title compound as a yellow solid. Purity 97%.
