Reaction Steps

Into a 100 mL round bottomed flask were placed 4-Chloro-6-methoxy-8-methylpteridin-7(8H)-one (2.00 g, 8.83 mmol, 1 equiv) and spiro[indoline-3,4′-piperidin]-2-one (2.14 g, 10.6 mmol, 1.2 equiv). Anhydrous n-butanol (20 mL) and triethylamine (2.46 mL, 2 equiv) were added and reaction mixture was heated to 80° C. with stirring. The reaction was complete as monitored by LC/MS after 5 hours. The solvent was stripped by rotary evaporation, and the residue rinsed with water (5 mL) to yield a tan precipitate, which was collected by vacuum filtration and rinsed with water to afford the desired product which was used directly without any further purification. 1H NMR (400 MHz, DMSO-d6): δ 10.49 (s, 1H), 8.39 (s, 1H), 7.49 (d, 1H), 7.20 (d, 1H), 6.97 (t, 1H), 6.87 (t, 1H), 4.53-4.45 (m, 4H), 3.80 (s, 3H), 3.55 (s, 3H), 1.93-1.80 (m, 4H). MS (EI) for C20H20N6O3: 393 (MH+).
