Reaction Steps

To a stirred solution of β-alanine tert-butyl ester hydrochloride (7.1 g, 39.2 mmol) and triethylamine (14.2 mL, 107 mmol) in dry acetonitrile (100 mL) was added 3-(bromomethyl)benzonitrile (7.0 g, 35.7 mmol) in portions over 10 minutes at 0° C. After being stirred at RT for 5 hours, the reaction mixture was diluted with water (100 mL) and extracted with dichloromethane (2×100 mL) The organic layers were combined, dried using sodium sulphate and concentrated under reduced pressure. The residue was purified by flash chromatography affording the title compound as a pale yellow liquid. 1H NMR (DMSO-d6, 400 MHz) δ 7.75 (s, 1H), 7.66 (m, 2H), 7.50 (m, 1H), 3.71 (s, 2H), 2.64 (t, 2H), 2.32 (m, 2H), 1.37 (s, 9H).
