72.3 g of N-benzoyl-3-hydroxy-3,3-diphenylpropylamine are added portionwise to the suspension of 16.3 g of lithium aluminum hydride in 1.6 lt of diethyl ether while stirring and cooling with an ice-bath. The mixture is stirred for 2 hours while warming to room temperature and 3 hours while refluxing. It is cooled again and 16.3 g of water, 16.3 ml of 15% aqueous sodium hydroxide and 49 ml water was added in this order, filtered and the residue washed 3 times with 300 ml of warm chloroform. The combined filtrates are dried and evaporated, to yield the N-benzyl-3-hydroxy-3,3-diphenylpropylamine melting at 145°-146°.
