The synthetic route is as follows., 937046-98-5
A solution of 7-bromopyrrolo[2,1-f][1,2,4]triazin-4-amine (120 mg, 0.563 mmol) in N,N-dimethylformamide (2.5 mL) was treated with 4-methoxybenzyl chloride (0.168 mL, 1.23 9 mmol), then with cesium carbonate (459 mg, 1.408 mmol), added in one portion. The mixture was stirred at room temperature for 22 h. The mixture was dilutedwith water and extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to provide a yellow semisolid. The material was chromatographed on an ISCO Companion 4 g silica gel column and eluted with EtOAc/hexane gradient (5-30%). The product containing fractions werecollected and concentrated to give 7-bromo-N,N-bis(4-methoxybenzyl)pyrrolo[2,1-f] [1,2,4]triazin-4-amine (147.8 mg, 97% purity, 0.316 mmol, 56% yield). Mass spectrum m/z 453, 455 (M+H). ?H NMR (400MHz, chloroform-d) oe 8.14 (s, 1H), 7.23 (d, J=8.6 Hz, 4H), 6.93-6.88 (m, 4H), 6.61 (d, J=1.3 Hz, 2H), 4.94 (s, 4H), 3.83 (s, 6H).
