(S)—N-(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)-1-(tetrahydro-2H-pyran-4-yl)methanesulfonamide (50 mg, 0.05 mmol, 80% purity) was treated with boron tribromide (1M in dichloromethane, 2.0 ml, 2.0 mmol) with dichloromethane (1.0 ml) as a solvent according to the method described in Example 23. and then with a solution of ammonia (7N in methanol, 5.0 ml, 35.0 mmol) according to the method described in Example 27. The residue was purified using SP1® Purification System (reverse phase, 0% to 100% water-acetonitrile/methanol 1:1) to obtain 6 mg (16% yield) of the title compound.
