Reaction Steps

1-(5-Isopropyl-4-methylsulfanylpyrrolo[2,1-f][1,2,4]triazin-6-yloxy)-propan-2-ol (262 mg, 0.93 mmol, obtained from Example 25 using procedure in Step B of Example 7) and 1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-5-ylamine (290 mg, 0.93 mmol) were dissolved in chloroform and m-chloroperbenzoic acid (60%, 535 mg, 1.86 mmol) was added. The mixture was heated at 120° C. for 10 min in a Personal Chemistry Smith Enrys Optimizer™ microwave oven. The solution was evaporated in vacuo and the residue was purified by preparative HPLC. The isolated product was dissolved in of THF (10 mL) and TBAF (1.0 M, 0.2 mL, 0.2 mmol) was added. The mixture was stirred for 5 min. and the solvent was evaporated in vacuo. The residue was purified by preparative HPLC to afford the title compound (3 mg, 1%).
