6-chloro-3,4-dihydro-1H-quinolin-2-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A reaction flask was charged with 6-chloro-3,4-dihydro-1H-quinolin-2-one (107LH30) (0.100 g, 0.55 mmol) in dry DMF (2 mL) under Argon. NaH (60% in oil, 0.024 g, 0.60 mmol) was added and the mixture was stirred at rt for 0.5 h. Then 1-bromo-3-chloropropane (0.087 g, 0.55 mmol) was added followed by stirring at 30° 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 crude material was dissolved in MeCN (3 mL) followed by addition of 4-butylpiperidine (0.078 g, 0.055 mmol), KI (0.166 g, 1.00 mmol), and K2CO3 (0.138 g, 1.00 mmol) and shaken at 50° for 2 days. 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 prep RP-HPLC to give the title compound (107LH36) (0.047 g, 24%). 1H NMR (CD3OD) δ 7.25-7.13 (m, 3H), 3.96 (t, J=7.2 Hz, CH2), 2.95-2.86 (m, 4H), 2.61-2.57 (m, 2H), 2.45-2.41 (m, 2H), 2.04-1.98 (m, 2H), 1.87-1.79 (m, 2H), 1.28-1.18 (m, 9H), 0.90 (t, J=7.0 Hz, CH3); 13C NMR (CD3OD) δ 172.3, 139.2, 130.2, 129.3, 128.9, 128.4, 117.8, 56.8, 54.9, 41.4, 37.2, 36.6, 32.9, 32.4, 30.0, 26.0, 25.3, 23.9, 14.4; HPLC-MS (ammonium acetate) [M+H+]=363.28. by stirring at 30° 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 crude material was dissolved in MeCN (3 mL) shaken at 50° for 2 days 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 prep RP-HPLC
