Reaction Steps

N-formyl-1,2-diphenyl-2-propylamine (23.6 g, 0.1 mol) was added to a stirred suspension of LiAlH4 (15.0 g, 0.395 mol) in 1 L of dry tetrahydrofuran. After 2 hours the mixture was heated at 35° C. for 22 hours, then refluxed for 2 hours, and allowed to cool to room temperature. Water was added to decompose the excess LiAlH4, and the mixture filtered to remove the solid salt. Evaporation of the solvent gave 23.0 g of the crude product as a yellow oil. This was dissolved in 180 ml of ethyl acetate and 20 ml of isopropanol and acidified with HCl gas. Upon standing a white solid crystallized which was collected by filtration and vacuum dried at 65° C. to give 21.7 g (84% of N-methyl-1,2-diphenyl-2-propylamine hydrochloride, mp 200°-201° C.
