Phenethylamine → Methyl 7-[(2-phenylethyl)amino]heptanoate

Participants

Reaction Steps

To a mixture of 2-penylethylamine (1.09 g, 9 mmol) and triethylamine (1.37 g, 13.5 mmol) in toluene (50 mL) was added methyl 7-bromoheptanoate (2.0 g, 9 mmol) and refluxed overnight. The reaction mixture was filtered and concentrated. Flash column chromatography over silica gel using 100% ethyl acetate yielded a yellow oil (0.62 g, 20%) NMR (250 MHz, CDCl3), 1.12-1.40 (4H, m), 1.40-1.72 (4H, m), 2.29 (2H, t), 2.63 (2H, t), 2.75-2.96 (4H, m), 2.96-3.1 (1H, br s), 3.66 (3H, s), 7.00-7.3 (5H, m).
