A solution of 0.15 g of 5-bromo-3,4-dihydroisoquinolin-1(2H)-one in 5 cm3 of dimethylformamide is poured into a mixture containing 31 mg of sodium hydride (60% in oil) and 10 cm3 of dimethylformamide at a temperature close to 20 C. under an inert atmosphere. Then a solution of 0.2 g of 1-(1-bromoethyl)-4-fluorobenzene in 5 cm3 of dimethylformamide is poured into the reaction mixture. The latter is stirred for 20 h at a temperature close to 20 C. Water and ethyl acetate are added to the reaction mixture. After decanting, the organic phase is washed with a saturated aqueous solution of sodium chloride, dried over magnesium sulfate, filtered then concentrated using a rotary evaporator under reduced pressure (5 kPa). The 325 mg of crude product obtained are purified by filtration through a silica pellet (eluent: 20% ethyl acetate/80% cyclohexane). After concentrating the fractions under reduced pressure, 146 mg of 5-bromo-2-[1-(4-fluorophenyl)ethyl]-3,4-dihydroisoquinolin-1(2H)-one are obtained in the form of a thick pale yellow oil.NMR: ppm: 1.54 (d, J=7.3 Hz, 3H) 2.85 (m, 1H) 2.97 (m, 1H) 3.10 (m, 1H) 3.47 (m, 1H) 5.92 (q, J=7.3 Hz, 1H) 7.18 (t, J=8.8 Hz, 2H) 7.33 (t, J=8.1 Hz, 1H) 7.41 (dd, J=8.8, 5.9 Hz, 2H) 7.78 (dd, J=8.1, 1.4 Hz, 1H) 7.98 (dd, J=8.1, 1.4 Hz, 1H)LC-MS-DAD-ELSD: [M+H]+ m/z=348, 1109230-25-2
