(S)-1-(3-Methoxy-4-(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)urea (34 mg, 0.05 mmol) was treated with boron tribromide (1M in dichloromethane, 1.5 mL, 1.5 mmol) in dichloromethane (1.0 mL) and then with a solution of ammonia (7N in methanol, 5.0 mL, 35.0 mmol) according to the method described in Example 41. The residue was purified using SP1® Purification System (0% to 10% dichloromethane-methanol) to obtain 3 mg (12% yield) of the title compound.
