Procedure

Benzoyl chloride (1 49g) was added to 3-dimethylamino-1,1-diphenyl-propan-2-ol (2,55g) in dry pyridine (10 ml.) and the solution allowed to stand for 4 hours. Pyridine was removed by evaporation and the residue dissolved in dilute hydrochloric acid and ether. Basification of the acid extract and isolation through ether in the usual manner gave 2-benzoyloxy-3-dimethylamino-1,1-diphenyl-propane (3.47g . 99%), m.p. 90°- 91°.
