Procedure

N-[2-(4-(benzoxazol-2-yl)benzyloxy)ethyl]-2-[3-(4-methylphenyl)prop-2-ynyloxy]ethanamine hydrochloride (125 mg) is dissolved in MeOH (12 ml) in an argon atmosphere and then 27 mg Pd/C catalyst is added. H2 is bubbled into the reaction mixture for 1 minute and stirred under H2 for 20 minutes. The mixture is purged with argon and filtered through celite and washed with MeOH and THF. Several drops of HCl/EtOH are added until acidic and the mixture concentrated to dryness to obtain N-[2-(4-(benzoxazol-2-yl)benzyloxy)ethyl]-2-[3-(4-methyl-phenyl)propoxy]ethanamine hydrochloride as a white solid. (m.p. 138°-139° C.).
