Reaction Steps

N′-[3-Methoxy-4-(4-{[(1S)-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]-N,N-dimethylsulfamide (73 mg, 0.06 mmol, 57% 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 1 mg (2% yield) of the title compound.
