Benzene, (3-bromopropoxy)- → N-(3-Phenoxypropyl)-1,1-dimethyl-2-(4-methoxyphenyl)ethylamine Hydrochloride

Participants

Reaction Steps

To a stirred suspension of 50% KF-Celite (0.35 g, 3 mmol) in anhydrous acetonitrile (10 mL) was added 1,1-dimethyl-2-(4-methoxyphenyl)ethylamine (0.27 g, 1.5 mmol) and 3-phenoxypropyl bromide (0.484 g, 2.25 mmol). The reaction mixture was refluxed under nitrogen for 6 hours, followed by stirring at room temperature for 62 hours. The mixture was filtered and the filtrate, was evaporated. The hydrochloride was prepared by dissolving the residue in HCl/methanol. The resulting solution was concentrated and dried on a lyophilizer. The residue was redissolved in dry methanol and diluted with diethyl ether, which caused precipitation of 210 mg of the title compound as a white solid: GC/EI-MS, m/z (rel. int.) 298 (M−15, 2), 193 (15), 192 (100), 120 (13), 107 (5), 98 (9), 77 (8), 72 (7), 71 (8), 70 (6), 41 (4).
