A 4 mL vial was charged with 1-(3-chloropropyl)-5-methyl-3,4-dihydro-1H-quinolin-2-one (107LH27-11,3) (0.057 g, 0.24 mmol), 4-butylpiperidine (0.042 g, 0.30 mmol), KI (0.083 g, 0.50 mmol), and K2CO3 (0.069 g, 0.50 mmol) in MeCN and shaken at 50°. 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; EtOAc, MeOH/EtOAc 1:4) to give the title compound (107LH28) (0.060 g, 74%). 1H NMR (CD3OD) d 7.15 (t, J=8.0 Hz, 1H), 7.03 (d, J=8.2 Hz, 1H), 6.92 (d, J=7.4 Hz), 4.00 (t, J=7.2 Hz, CH2), 3.10 (d, J=12.1 Hz, 2H), 2.87-2.83 (m, 2H), 2.66-2.62 (m, 2H) 2.59-2.55 (m, 2H), 2.31-2.25 (m, 2H), 2.29 (s, CH3), 1.93-1.87 (m, 2H), 1.76 (d, J=11.7 Hz, 2H), 1.31-1.24 (m, 9H), 0.90 (t, J=6.8 Hz, CH3); 13C NMR (CD3OD) d 172.7, 140.2, 137.0, 128.1, 126.6, 126.5, 114.5, 56.5, 54.6, 41.2, 37.0, 36.0, 32.2, 32.2, 30.0, 25.0, 23.9, 22.4, 19.7, 14.4; HPLC-MS (ammonium acetate) [M+H+]=343.36.
