The title product was obtained following the procedure of example 27 by reacting 7-amino-1-(4-methyl-1-piperazinyl)-naphthalene (0.225 g, 0.93 mmol), 2-fluoronitrobenzene (0.255 g, 1.8 mmol), and 4-dimethylaminopyridine (0.167 g, 1.37 mmol) in dry DMF (5 mL) with an overnight reflux. The product was isolated by silica gel flash chromatography and recrystallization from ethyl acetate/ether to yield 0.024 g (7%) of the title compound as orange crystals: mp 87°-94° C.; 1H NMR δ 9.70 (br s, 1H), 8.26 (dd, J=1.5, 8.5 Hz, 1H), 8.07 (d, J=2 Hz, 1H), 7.87 (d, J=8.5 Hz, 1H), 7.57 (s, J=8 Hz, 1H), 7.44-7.32 9m, 4H), 7.16 (dd, J=1,7.5 Hz, 1H), 6.82 (dd, J=6.5, 8.5 Hz, 1H), 3.15 (br s, 4H), 2.70 (br s, 4H), 2.41 (s, 3H). HRMS m/e calculated for C21H22N4O2 ; 362.1738. Observed m/e: 362.1736.
