Reaction Steps

To a solution of 4-bromo-1-bromomethyl-2-ethyl-benzene (2.00 g, 7.19 mmol) in CH2Cl2 (30 mL) was added dropwise pyrrolidine (1.19 mL, 14.4 mmol). The mixture was stirred for 15 hours, and then partitioned between Et2O and H2O. The organic layer was washed with brine, dried over MgSO4, and concentrated to yield a yellow oil (1.3 g, 68%). 1H NMR (300 MHz, CDCl3): δ 1.19 (t, J=7.5 Hz, 3 H), 1.76 (m, 4 H), 2.47 (m, 4 H), 2.69 (q, J=7.5 Hz, 2 H), 3.54 (s, 2 H), 7.19 (m, 1 H), 7.25 (m, 1 H), 7.29 (d, J=1.9 Hz, 1 H).
