Versuchsvorschrift

Excess N methyl-N-ethylamine was added to a solution of 1,1 -diphenyl-3-bromo-propan-2-ol (2 g.) in ethanol. After 60 hours the solution was evaporated and the residue was evaporated and the residue dissolved in dilute hydrochloric acid and ether. Basification of the acid extract and subsequent isolation through ether in the usual manner gave 3-(N-methyl-N-ethylamino)-1,1 -diphenyl-propan-2-ol isolated as the hydrochloride (1 25 g., 60%), m.p. 159° - 161°.
