Procedure

To a solution of 1,2-epoxydodecane (1.84 g, 10.0 mmol) in anhydrous acetonitrile (5 mL) is added anhydrous magnesium perchlorate (2.23 g, 10.0 mmol). After 15 minutes, benzylamine (1.1 mL, 10.0 mmol) is added dropwise and the solution is stirred for 50 hours at room temperature. The mixture is concentrated, diluted with water, and extracted twice with ethyl acetate. The combined organic extracts are washed with water, brine, dried over magnesium sulfate, and concentrated to afford 2.9 g of the title compound as a white solid; 1H NMR (200 MHz, CDCl3)δ7.38-7.25 (m, 5 H), 3.87 (d, J=2 Hz, 2 H), 3.80-3.65 (m, 1 H), 3.00-2.75 (m, 3 H), 2.60-2.45 (m, 1 H), 1.40-1.20 (m, 18 H), 0.88 (t, J=7 Hz, 3 H).
