(S)-4-Methoxy-N-(3-(4-((1-(5-methyl-4-oxo-3-phenyl-3,4-dihydropyrrolo[2,1-f][1,2,4]triazin-2-yl)ethyl)amino)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)phenyl)benzenesulfonamide (57 mg, 0.05 mmol) was treated with boron tribromide (1M in dichloromethane, 536 μL, 0.54 mmol) in dichloromethane (1.15 mL) and then with a solution of ammonia (7N in methanol, 1.15 ml, 6.05 mmol) according to the method described in Example 27. The residue was purified using SP1 ® Purification System (0% to 6% dichloromethane-2-propanol) to obtain 25 mg (72% yield) of the title compound.
