Procedure

A 4 mL vial was charged with (S)-1-(3-iodo-2-methylpropyl)-3,4-dihydro-1H-quinolin-2-one (122LH18) (0.185 g, 0.56 mmol) and 3-pentyl-8-azabicyclo[3.2.1]octane (0.112 g, 0.62 mmol) in MeCN (0.5 mL) and shaken at 40° for 20 h. The reaction mixture was quenched with water, basified with ammonium hydroxide, 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; n-heptane/EtOAc 4:1) to give the title compound (107LH55) (0.075 g, 35%). 1H NMR (CD3OD) δ 7.28-7.18 (m, 3H), 7.01 (t, J=7.2 Hz, 1H), 4.03 (d, J=7.0 Hz, 2H), 3.11-3.04 (m, 2H), 2.90-2.85 (m, 2), 2.64-2.56 (m 2H), 2.28-2.11 (m, 4H), 1.97-1.84 (m, 3H), 1.66-1.54 (m, 3H), 1.42-1.21 (m, 10H), 0.90-0.85 (m, 2 CH3); 13C NMR (CD3OD) δ 173.1, 140.3, 129.1, 128.4, 128.3, 124.3, 117.1, 61.4, 60.2, 58.3, 46.4, 39.5, 37.1, 37.0, 33.1, 32.9, 32.2, 29.5, 29.4, 28.5, 27.9, 26.3, 23.7, 17.1, 14.4.
