Versuchsvorschrift

To a solution of 3-(benzyl)benzamide (0.0094 moles) from Step B in 70 of toluene was added 8 mL of Red-Al® (65+wt. % solution of sodium bis(2-methoxyethoxy)aluminum hydride in toluene, Aldrich) (CAUTION—reaction very exothermic). The reaction mixture was then heated at 60° C. for 2 hours and then poured over ice. The resulting mixture was extracted with ethyl acetate and the combined extracts were washed with water and brine. The organic layer was extracted with 1N HCl and the aqueous layer washed with ethyl acetate. The pH of the aqueous layer was then adjusted to about 9.0 with 1N NaOH and extracted with ethyl acetate. The organic extracts were washed with water and brine and then concentrated to give 3-(benzyl)benzyl amine.
