Add methallyl chloride (68.8 g, 0.760 mol, Aldrich) to a mixture of N-benzylethanolamine (100 g, 0.663 mol) and potassium carbonate (139 g, 1.00 mol) in water (600 mL). Heat the mixture to 62° C. for 23 h and then transfer to a separatory funnel. Extract the product with tert-butyl methyl ether (500 mL). Dry, filter, and concentrate the organic solution to give the title compound (131 g, 96%) as a colorless liquid. 1H NMR (DMSO-d6, 400 MHz) δ 7.20-7.33 (5H, m), 4.92 (1H, br s), 4.83 (1H, br s), 4.35 (1H, t), 3.53 (2H, s), 3.44-3.50 (2H, m), 2.94 (1H, s), 2.42 (2H, t), 1.69 (1H, s).
