Reaction Steps

(S)-2-(1-Aminoethyl)-5-((2-hydroxyphenyl)thio)-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (183 mg, 0.36 mmol) was treated with 4-amino-6-chloropyrimidine-5-carbonitrile (84 mg, 0.54 mmol), and N,N-diisopropylethylamine (380 μl, 2.18 mmol) in tert-butanol according to the method described in Example 17. The crude was purified by reverse phase using SP1® Purification System to give 69 mg (38% yield) of the title compound as a white solid. Purity 100%.
