실험 절차

A 4 ml vial was charged with 1-(3-chloropropyl)-6,7-difluoro-3,4-dihydro-1H-quinolin-2-one (78 mg, 0.30 mmol), 4-cyclopropylmethoxypiperidine (145LH49) (42 mg, 0.27 mmol), NaI (75 mg, 0.50 mmol), and K2CO3 (69 mg, 0.50 mmol) in CH3CN/DMF (1 ml, 50:50). The reaction was shaken at 50° C. for 3 days and the reaction was poured into water and extracted with EtOAc. The organic phase was washed with brine, dried (Na2SO4), filtered, and concentrated under reduced pressure. The oily residue was purified by ion-exchange column chromatography followed by flash column chromatography (SiO2; EtOAc) to yield the title compound as an oil (83 mg, 0.22 mmol, 81%). 1H NMR (CDCl3) δ 6.90 (dd, J=6.8, 12.0 Hz, 1H), 6.82-6.75 (m, 1H), 3.73 (t, J=7.2 Hz, 2H), 3.22-3.13 (m, 1H), 3.11 (d, J=6.8 Hz, 2H), 2.69-2.54 (m, 4H), 2.47-2.41 (m, 2H), 2.23-2.17 (m, 2H), 2.01-1.91 (m, 2H), 1.78-1.58 (m, 4H), 1.52-1.40 (m, 2H), 0.94-0.82 (m, 1H), 0.44-0.28 (m, 2H), 0.06 (−) 0.03 (m, 2H); 13C NMR (CDCl3) δ 166.4, 146.1 (dd, J=13, 243 Hz), 142.3 (dd, J=13, 243 Hz), 133.3 (dd, J=3, 8 Hz), 119.4 (dd, J=2, 5 Hz), 113.3 (d, J=18 Hz), 102.0 (d, J=22 Hz), 71.5 (br), 69.5, 52.2, 48.3, 38.0, 28.6, 28.2, 21.9, 21.7, 7.9, 0.0; HPLC-MS (ammonium acetate) [M+H]+=379.29.
