Reaction Steps

(S)-2-(1-Aminoethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (400 mg, 1.49 mmol) was treated 4-chloro-5-iodopyrimidine (538 mg, 2.24 mmol), cesium fluoride (453 mg, 2.98 mmol) and N,N-diisopropylethylamine (1.3 mL, 7.46 mol) according to Preparation 13. The residue was purified by reverse phase using SP1® Purification System to give 230 mg (33% yield) of the title compound as a solid. Purity 100%.
