Reaction Steps
A mixture of 4-bromobenzyl bromide (500 mg, 2.0 mmol) and 4,4-dimethylpiperidine (249 mg, 2.2 mmol) and potassium carbonate (331 mg, 2.4 mmol) in acetonitrile (20 mL) was heated under reflux for 2 h. The reaction mixture was then cooled to ambient temperature and the reaction mixture concentrated under reduced pressure. The resultant oil was loaded onto an SCX-2 cartridge (10 g) and eluted with 2N ammonia in methanol to afford the title compound (323 mg, 57%). 1H NMR (CDCl3, 300 MHz): 7.42 (d, J=8.31 Hz, 2H), 7.19 (d, J=8.24 Hz, 2H), 3.44 (s, 2H), 2.35 (t, J=5.44 Hz, 4H), 1.37 (t, J=5.60 Hz, 4H), 0.90 (s, 6H).
