反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A reaction flask was charged with 6-fluoro-3,4-dihydro-1H-quinolin-2-one (0.180 g, 1.09 mmol) in dry DMF (2 mL) under Argon. NaH (60% in oil, 0.048 g, 1.20 mmol) was added and the mixture was stirred at rt for 0.5 h. Then 1-bromo-3-chloropropane (0.180 g, 1.14 mmol) was added followed by stirring at rt for 20 h. The reaction mixture was quenched with water, and the product extracted into EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated. The product was purified by flash CC (SiO2; DCM) to give the title compound (92LH79) (0.193 g, 73%). 1H NMR (CDCl3) δ 7.02-6.88 (m, 3H), 4.09-4.05 (m, 2H), 3.61 (t, J=6.3 Hz, CH2), 2.87 (t, J=6.7 Hz, CH2), 2.65-2.61 (m, 2H), 2.16-2.09 (m, 2H); 13C NMR (CDCl3) δ 169.8, 158.4 (J=242.9 Hz), 135.7 (J=2.7 Hz), 128.5 (J=7.7 Hz), 115.7 (J=8.1 Hz), 115.1 (J=22.7), 113.8 (J=22.3 Hz), 42.6, 40.3, 31.5, 30.1, 25.5. by stirring at rt for 20 h The reaction mixture was quenched with water the product extracted into EtOAc The combined organic layers were dried over Na2SO4 filtered concentrated The product was purified by flash CC (SiO2; DCM)

The mixture was concentrated, and sat aqueous Na2CO3 (25 mL) was added followed by extraction into an organic mixture (MeOH:CH2Cl2; 1:10, 3×50 mL). The combined organic phase was dried (Na2SO4), filtered, concentrated under reduced pressure and purified by flash CC (SiO2; CH2Cl2/MeOH 20:1) to give the title compound (0.056 g, 31%). 1H NMR (DMSO-D6) δ 11.8 (brs, 1H), 7.85 (d, J=9.4 Hz), 7.50 (dd, J=2.8, 9.2 Hz), 7.43-7.37 (m, 1H), 7.37-7.25 (m, 1H), 6.54 (d, J=9.4 Hz). the resulting solution was refluxed for 16 h The mixture was concentrated was added followed by extraction into an organic mixture (MeOH:CH2Cl2; 1:10, 3×50 mL) The combined organic phase was dried (Na2SO4) filtered concentrated under reduced pressure purified by flash CC (SiO2; CH2Cl2/MeOH 20:1)
