Dimethylformamide → 6-(4-Biphenylyl)methoxy-2-[3-(N,N-dimethylamino)propyl]tetralin hydrochloride

Participants

Reaction Steps

60% Oily sodium hydride (0.258 g) was added to a DMF solution (20 ml) of 2-[3-(N,N-dimethylamino)propyl]-6-hydroxytetralin (1.00 g) at 0° C. The reaction mixture was warmed to room temperature, and stirred for 30 minutes. This was again cooled to 0° C., and 4-(chloromethyl)biphenyl (1.04 g) as added thereto, and then stirred at room temperature for 4 hours. Water was added to the reaction mixture, which was then extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, then dried, and concentrated. The residue was purified by alumina column chromatography (eluent: toluene alone to toluene/ethyl acetate=1/1), and then processed with 4 N hydrochloric acid-ethyl acetate to form a hydrochloride. The thus-formed salt was recrystallized from methanol-diisopropyl ether to obtain the entitled compound (1.30 g).
