Reaction Steps

2,4-diamino-8-(2-hydroxyethoxy)-5H-chromeno[2,3-b]pyridine-3-carbonitrile was prepared from 2,4-diamino-8-hydroxy-5H-chromeno[2,3-b]pyridine-3-carbonitrile in the same manner as described in Example 10 using 2-bromoethanol in lieu of 2-bromoethyl-ethylether. The product was isolated as a tan solid (120 mg, 35% yield). 1H NMR (400 MHz, DMSO) δ 7.025 (d, 1H), 6.670 (d, 1H), 6.550 (d, 1H), 3.931 (t, 2H), 3.662 (t, 2H), 3.546 (s, 2H); m/z 413 (M+H).
