A solution of 2 (2.00 g, 10.8 mmol), (2-bromoethoxymethyl)benzene (2.31 g, 10.8 mmol), and triethylamine (4.5 ml, 32.4 mmol) in dichloromethane (30 mL) was stirred at room temperature overnight. Solvent was evaporated and the residue was purified by Flash™ chromatography (BIOTAGE, Inc) (9.3:0.7 dichloromethane/methanol, v/v) to provide 3a (1.3 g, 42%) as a yellow oil. 1H NMR (300 MHz, CD3OD) δ 1.30 (m, 5H), 1.66 (m, 2H), 1.87 (d, 2H), 2.37 (m, 2H), 2.58 (m, 2H), 3.04 (m, 2H), 3.39 (m, 2H), 3.65 (s, 3H), 3.80 (m, 2H), 4.55 (s, 2H), 7.37 (m, 5H). m/z (ESI): 320 [C19H29NO3+H]+.
