Reaction Steps
A 4 mL vial was charged with 1-(3-chloropropyl)-7-fluoro-6-methyl-3,4-dihydro-1H-quinolin-2-one (112KK01) (0.047 g, 0.18 mmol), 4-butylpiperidine (0.039 g, 0.28 mmol), NaI (0.100 g, 0.67 mmol), and K2CO3 (0.075 g, 0.54 mmol) in MeCN (2 mL) and shaken at 50° for 20 h. The reaction mixture was quenched with water, and the product extracted into EtOAc. The combined organic layers were purified by cation exchange CC followed by purification by flash CC (SiO2; MeOH/DCM 1:10) to give the title compound (112KK06) (0.022 g, 34%). 1H NMR (CD3OD) δ 7.05 (d, J=8.4 Hz, 1H), 6.93 (d, J=11.7 Hz, 1H), 3.93 (t, J=7.2 Hz, CH2), 2.93 (d, J=11.1 Hz, 2H), 2.83 (t, J=6.9 Hz, CH2), 2.60-2.56 (m, 2H), 2.44-2.40 (m, 2H), 2.19 (D, J=1.8 Hz, CH3) 2.03-1.98 (m, 2H), 1.86-1.79 (m, 2H), 1.69 (d, J=11.0 Hz, 2H), 1.31-1.19 (m, 9H), 0.89 (t, J=6.6 Hz, CH3); 13C NMR (CD3OD) δ 172.4, 161.7 (d, J=241.0 Hz), 139.5 (d, J=10.0 Hz), 131.7 (d, J=6.1 Hz), 123.5 (d, J=3.6 Hz), 119.9 (d, J=17.4 Hz), 104.0 (d, J=28.1 Hz), 56.8, 55.0, 41.5, 37.3, 36.7, 33.0, 32.8, 30.1, 25.5, 25.3, 23.9, 14.4, 13.7.
