Reaction Steps

(S)-2-(1-Aminoethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (330 mg, 1.08 mmol) was treated with 5-bromo-4-chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (430 mg, 1.19 mmol), cesium fluoride (33 mg, 0.22 mmol), N,N-diisopropylethylamine (1.1 mL, 6.49 mol) and 1-butanol according to Preparation 13. The residue was purified using SP1® Purification System (0% to 30%, hexane-ethyl acetate) to give 0.24 g (38% yield) of the title compound. Purity 100%.
