To the stirred solution of 15.6 g of N-benzyl-3-hydroxy-3,3-diphenylpropylamine in 7.0 g of di-isopropylethylamine and 150 ml of methylene chloride, that of 5.88 g of chloroacetyl chloride in 50 ml of methylene chloride is added dropwise while stirring and cooling with an ice-bath. Thereupon the solution is stirred for 15 minutes at 0°-5° and washed successively with N hydrochloric acid, 10% aqueous sodium bicarbonate and finally with saturated aqueous sodium chloride. The organic layer is separated, dried, filtered and evaporated, to yield the N-benzyl-N-chloroacetyl-3-hydroxy-3,3-diphenylpropylamine showing in the I.R.-spectrum a strong band at 1640 cm-1.
