Reaction Steps

To morpholine (5 mL) was added 7-(2-chloro-ethoxy)-6-methoxy-quinazolin-4-ol (600 mg, 2.36 mmol) from Example 35A and the mixture heated at 100° C. for 4 hours. After cooling to room temperature, the mixture was diluted with DCM and filtered. The resulting solid was washed with MeOH and H2O to give 4-hydroxy-6-methoxy-7-(2-morpholinoethoxy)quinazoline (328 mg, 1.07 mmol, 46%). 1H NMR (300 MHz, DMSO-d6) δ 12.08 (br s, 1H), 7.98 (s, 1H), 7.44 (s, 1H), 7.17 (s, 1H), 4.23 (t, 2H), 3.87 (s, 3H), 3.58 (t, 4H), 3.41-3.32 (m, 4H), 2.75 (t, 2H); LC-MS (ESI) m/z 306 (M+H)+.
