Dimethylamine → 1-Butanamine, 4-(2-(2-(2-chlorophenyl)ethyl)phenoxy)-N,N-dimethyl-, hydrochloride

Participants

Reaction Steps

A solution of 3.0 g of 2-(4-bromobutoxy)-2'-chlorobibenzyl in 15 ml of 50% aqueous dimethylamine solution and 15 ml of tetrahydrofuran was stirred at room temperature for 5 hours. The reaction mixture was concentrated and to the concentrate was added 2 N-NaOH solution. The product was extracted with ether, washed well with saturated sodium chloride solution and then dried over anhydrous sodium sulfate. To the ether solution was added 20% ethanolic hydrogen chloride to yield white crystals. Recrystallization from ethanol-ether gave 2.8 g (93% yield) of 2-(4-dimethylaminobutoxy)-2'-chlorobibenzyl hydrochloride, m.p. 122°-123° C.
