Procedure

To the solution of 58.0 g of 3-hydroxy-3,3-diphenylpropylamine in 700 ml of methylene chloride and 30.5 g of pyridine, that of 37.5 g of benzoyl chloride in 300 ml of methylene chloride is added dropwise during 2 hours while stirring and cooling with an ice-bath. Stirring is continued for 1 hour at 0°-5°, the mixture washed twice with 200 ml of N hydrochloric acid, 150 ml of 5% aqueous sodium hydroxide and 25 ml of water each, dried, evaporated and the residue triturated with diethyl ether, to yield the N-benzoyl-3-hydroxy-3,3-diphenylpropylamine melting at 140°-141°.
