Reaction Steps

(S)-2-(1-((5-(1-(3-Methoxyphenyl)-1H-pyrazol-3-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (9 mg, 0.01 mmol) was treated with boron tribromide (1M in dichloromethane, 1 mL, 1.00 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 (reverse phase, 0% to 100% water-methanol/acetonitrile 1:1) to obtain 4 mg (47% yield) of the title compound.
