A solution of 4-chloro-7-(3-chloro-propoxy)-quinazoline (synthesized as reported in J. Med. Chem. 2007, 50, 2213-2224) (100 mg, 0.389 mmol), 2-(4-aminophenyl)ethyl amine (63.6 mg, 0.467 mmol) and triethylamine (118.1 mg, 1.167 mmol) in ethanol (3 mL) was heated at 120° C. for 3 hours. The solution was cooled and the solid formed was filtered, washed with ethanol and then with dichloromethane to give the title compound as light yellow solid product (34 mg, 25%). 1H-NMR (300 MHz, CD3OD): 7.93-8.37 (s, 1H), 7.96 (d, J=9.0 Hz, 1H), 7.07-7.13 (m, 2H), 7.00-7.03 (d, J=8.1 Hz, 2H), 6.66-6.69 (d, J=8.4 Hz, 2H), 4.24-4.28 (t, 2H), 3.71-3.81 (m, 4H), 2.84-2.89 (t, 2H), 2.27-2.31 (m, 2H). LC-MS (ESI) m/z 357.3 (M+1).
