(S)-4-((4-Methoxybenzyl)amino)-6-((1-(5-methyl-4-oxo-3-phenyl-3,4-dihydropyrrolo[2,1-f][1,2,4]triazin-2-yl)ethyl)amino)pyrimidine-5-carboxylic acid (300 mg, 0.51 mmol) was dissolved in 7 mL dimethylformamide. N,N-Diisopropylethylamine (150 μl, 1.10 mmol) and HATU (400 mg, 1.05 mmol) were added and the reaction mixture was stirred at room temperature for 30 min. Then, 3-methoxyaniline (95 μl, 0.85 mmol) was added and the reaction mixture stirred at room temperature overnight. The crude was diluted with water and extracted with ethyl acetate. The organic layer was washed with water, brine, dried over sodium sulphate and concentrated under reduced pressure. A semi-solid was obtained and purified using SP1® Purification System (0% to 50%, hexane-ethyl acetate) to obtain 265 mg (82% yield) of the title compound. Purity 100%.
