In the second step, benzophenone oxime (900 mg) was hydrogenated with a solution of concentrated hydrochloric acid (1.84 mL) in ethanol (50 mL) at atmospheric pressure in the presence of 10% Pd/C catalyst (100 mg). Upon completion of the reaction, the reaction mixture was filtered to remove the catalyst and the filtrate was subsequently concentrated. The concentrated residue was suspended in ethyl acetate and the suspension was filtered again to give the final diphenylmethylamine hydrochloride (2.17 g) as a white solid.
