3-(4-sec-butylphenyl)-2-(6-(hydroxymethyl)pyridin-3-yl)quinazolin-4(3H)-one (0.176 g, 0.46 mmol) was dissolved in CH2Cl2 (30 mL) under nitrogen and cooled to 0° C. Hünig's base (0.160 mL, 0.92 mmol) was added, followed by MsCl (0.042 mL, 0.55 mmol), and the mixture was stirred for 15 min at 0° C. Morpholine (0.400 mL) was added, the reaction was warmed to room temperature, and stirred for 2 hours, before concentration and purification by flash chromatography on silica gel, eluting with 100% ethyl acetate to 10% methanol/ethyl acetate, afforded the title compound (0.175 g, 984%). 1H-NMR (300 MHz, DMSO-6): δ8.48 (s, 1H), 8.22 (d, J=7.9 Hz, 1H), 7.90-7.95 (m, 1H), 7.79 (d, J=8.1 Hz, 1H), 7.60-7.68 (m, 2H), 7.22-7.27 (m, 3H), 7.10-7.16 (m, 2H), 3.49-3.54 (m, 6H), 2.55-2.63 (m, 1H), 2.19-2.29 (m, 4H), 1.33-1.56 (m, 2H), 1.13 (d, J=6.8 Hz, 3H), 0.62 (t, J=7.2 Hz, 3H). MS (APCI) m/z: 455 (M+H)+.
