Reaction Steps

To a suspension of (S)-2-(1-((5-(4-amino-2-methoxyphenyl)-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 (50 mg, 0.08 mmol) in water (0.40 mL) and acetic acid (0.20 mL) was added potassium isocyanate (19 mg, 0.23 mmol) according to the method described in Preparation 181 but stirring at 60° C. overnight. The residue was purified using SP1® Purification System (0% to 100% n-hexane-ethyl acetate) to obtain 34 mg (61% yield) of the title compound.
