Reaction Steps
To a solution of 4-[2-(pteridin-4-ylamino)ethyl]phenol (0.267 g, 1.0 mmol) and 2-chloropyrazine (0.114 g, 1.0 mmol) in anhydrous DMF (7 mL) was added 60% sodium hydride (NaH) in mineral oil (0.060 g, 1.5 mmol) portionwise. The mixture was stirred at 55° C. overnight and then at 70° C. for a total reaction time of 32 h. The solvent was removed in vacuo and the residue was suspended in H2O. The solid was collected by suction filtration, washed with H2O and Et2O, dried in a vacuum oven at 55° C. overnight to afford pteridin-4-yl-{2-[4-(pyrazin-2-yloxy)-phenyl]-ethyl}-amine (0.291 g, 84%) as a light brown solid: 1H NMR (300 MHz, CDCl3) δ 9.02 (d, J=1.9 Hz, 1H), 8.82 (s, 1H), 8.63 (d, J=1.9 Hz, 1H), 8.43 (d, J=1.5 Hz, 1H), 8.26 (d, J=2.4 Hz, 1H), 8.10 (dd, J=2.4, 1.5 Hz, 1H), 7.33 (d, J=8.4 Hz, 2H), 7.13 (d, J=8.4 Hz, 2H), 3.99 (dd, J=13.6, 6.9 Hz, 2H), 3.08 (t, J=6.9 Hz, 2H); ESIMS m/z 346.24 ([M+H]+).
