Reaction Steps

A solution of tert-butyl 3-(3,4-dihydroquinolin-1(2H)-yl)pyrrolidine-1-carboxylate (1.86 g, 6.15 mmol) in 15 mL of DMF was cooled to 0° C. then treated dropwise with NBS (1.09 g, 6.15 mmol) in 15 mL DMF. The reaction was stirred at 0° C. for 1.5 hours then treated with 100 mL H2O. The suspension was extracted with 2×150 mL EtOAc. The combined organic layer was rinsed with brine (3×20 mL), dried over Na2SO4, filtered and concentrated to give a viscous oil. This residue was subjected to flash chromatography on silica gel using 15% EtOAc/Hexanes to give a viscous oil (1.50 g, 63.8%). 1H-NMR (CDCl3) δ 7.13 (d, J=9.0 Hz, 1H), 7.07 (brs, 1H), 6.55 (d, J=9.0 Hz, 1H), 4.35-4.33 (m, 1H), 3.58-3.18 (m, 6H), 2.71 (t, J=6.3 Hz, 2H), 2.11-2.04 (m, 2H), 1.91-1.87 (m, 2H), 1.47 (s, 9H). MS (ESI): 325.1 and 327.1 (M+1, 100%).
