Reaction Steps

A reaction flask was charged with 7-fluoro-6-methyl-3,4-dihydro-1H-quinolin-2-one (97KK40) (0.102 g, 0.57 mmol) in dry DMF (5 mL) under an argon atmosphere. Washed NaH (0.015 g, 0.63 mmol) was added and the mixture was stirred at rt for 1 h. Then 1-chloro-3-iodopropane (0.104 g, 0.51 mmol) dissolved in DMF (1 mL) was added followed by stirring at rt for 20 h. The reaction mixture was quenched with water, and the product extracted into Et2O. The combined organic layers were washed with aqueous 4% MgSO4, dried over Na2SO4, filtered, and concentrated. The product was purified by flash CC (SiO2; DCM/n-heptane 2:1, DCM, MeOH/DCM 1:10) to give the title compound (112KK01) (0.050 g, 38%). 1H NMR (CDCl3) δ 6.95-6.93 (m, 1H), 6.73 (d, J=11.5 Hz, 1H), 4.03-4.00 (m, 2H), 3.59 (t, J=6.5 Hz, CH2), 2.83-2.79 (m, 2H), 2.62-2.58 (m, 2H), 2.20 (d, J=1.8 Hz, CH3), 2.13-2.07 (m, 2H).
