(S)—N-(5-(4-Amino-6-((1-(5-methyl-4-oxo-3-phenyl-3,4-dihydropyrrolo[2,1-f][1,2,4]triazin-2-yl)ethyl)amino)pyrimidin-5-yl)-2-ethylpyridin-3-yl)-4-methoxybenzenesulfonamide (146 mg, 0.22 mmol) was treated with boron tribromide (1M in dichloromethane, 700 μl, 0.70 mmol) in dichloromethane (1 ml) as a solvent according to the method described in Example 23. The residue was purified by reverse phase chromatography using SP1® Purification System to give 31 mg (22% yield) as a solid. Purity 100%.
