Procedure

To a solution of (E)-1-(1-(quinolin-6-ylmethyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl)ethanone O-2-hydroxyethyl oxime (example 23) (200 mg, 0.55 mmol) in THF (10 mL) were added triphenylphosphine (144 mg, 0.55 mmol), isoindoline-1,3-dione (81 mg, 0.55 mmol) and (E)-diisopropyl diazene-1,2-dicarboxylate (111 mg, 0.55 mmol) sequentially. The mixture was stirred at rt for 48 h and concentrated in vacuo. The residue was purified by column chromatography to afford 120 mg (42%) of the title compound. 1H-NMR (400 MHz, DMSO-d6). ppm 8.90 (s, 1H), 8.89 (m, 1H), 8.35 (d, 1H), 8.02 (m, 2H), 7.81 (d, 1H), 7.71 (m, 2H), 7.63 (m, 2H), 7.52 (dd, 1H), 6.19 (s, 2H), 4.53 (t, 2H), 3.97 (t, 2H), 2.20 (s, 3H). LCMS (method B): [MH]+=493, tR=2.52 min.
