실험 절차

3-Dimethylamino-propan-1-ol (251 μL, 2.14 mmol) and DEAD (973 μL, 2.14 mmol) were added to a solution of 4-bromo-3-methyl-phenol (200 mg, 1.07 mmol) and PPh3 (561 mg, 2.14 mmol) in THF (10 mL) at 0° C. The mixture was stirred for two hours and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to give [3-(4-bromo-3-methyl-phenoxy)-propyl]-dimethyl-amine (176 mg, 61%).
