Reaction Steps

To a solution of 2-[4-(4-bromo-butoxy)-3,5-dimethyl-phenyl]-5,7-dimethoxy-3H-quinazolin-4-one (494 mg, 1.07 mmol) in DMF (10 mL) was added pyrrolidine (609 mg, 8.57 mmol). The reaction mixture was stirred at room temperature for 16 hours. Water (100 mL) was added and the product was extracted with ethyl acetate (2×200 mL). The combined organic phase was washed with water, then brine, and dried over anhydrous Na2SO4. Solvent was evaporated to give the title compound as a white solid. Yield: 278 mg (57%). MP 180-181° C. 1H NMR (400 MHz, CDCl3): δ 7.68 (s, 2H), 6.83 (d, J=2.4 Hz, 1H), 6.46 (d, J=2.4 Hz, 1H), 3.97 (s, 3H), 3.92 (s, 3H), 3.83 (t, J=6.4 Hz, 2H), 2.56 (m, 6H), 2.36 (s, 6H), 1.88 (m, 2H), 1.79 (m, 6H). MS (ES) m/z: 452.21 (M+1).
