Reaction Steps

A mixture of 4-(3-Amino-phenoxy)-piperidine-1-carboxylic acid tert-butyl ester (94 mg, 0.32 mmol), Trifluoro-methanesulfonic acid 7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl ester (100 mg, 0.3 mmol), 1-Methoxy-2-propanol (0.3 mL, 3 mmol), and N,N-Diisopropylethylamine (2 mL, 10 mmol) was heated and let stir overnight at 80° C. Concentrated added Hydrogen Chloride (2 mL, 60 mmol) and stir at room temperature for half and hour. The reaction was concentrated, dissolved in 2 mL DMSO, filtered and placed onto the Gilson. The pure fractions were frozen and lypholyzed over night to give [7-(2-Methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-[3-(piperidin-4-yloxy)-phenyl]-amine
