Reaction Conditions

Reaction Steps

To a mixture of 1-bromo-4-(3-bromopropoxy)benzene (300 mg, 1.02 mmol) and tert-butyl piperazine-1-carboxylate (144 mg, 1.02 mmol) in acetonitrile (6.0 mL) was added Cs2CO3 (365 mg, 1.10 mmol). The mixture was stirred at 75° C. for 5 hours. The mixture was poured into ethyl acetate and washed with water. The organic phase was dried over sodium sulfate, filtered, and concentrated to give the title compound (300 mg, 75% yield) as a yellow oil. 1H NMR (400 MHz, CDCl3): δ 7.40 (d, 2H), 6.75 (d, 2H), 3.95 (m, 2H), 3.42 (m, 4H), 2.54 (t, 2H), 2.40 (m, 4H), 2.01-1.89 (m, 2H), 1.50-1.40 (s, 9H).
