Reaction Steps

A mixture of 3-bromomethyl-pentane (6.0 g, 36.4 mmol) and ethanolamine (13 mL, 218 mmol) in ethanol (45 mL) was heated at 75° C. for 16 h. The reaction mixture was concentrated and the resulting residue was diluted with DCM (70 mL). The organic layer was partitioned with water (70 mL) and the aqueous layer extracted with DCM. Combined organic layers, dried over magnesium sulfate, filtered, and concentrated to give the title compound as an oil (4.90 g). 1H NMR (d6-DMSO, 400 MHz) δ (ppm): 3.44 (t, J=5.6 Hz, 2H), 2.54 (t, J=6.0 Hz, 2H), 2.40 (d, J=5.6 Hz, 2H), 1.31-1.25 (m, 5H), 0.83 (t, J=6.8 Hz, 6H).
