Reaction Steps

N-trityl-N-[2-(4-(benzoxazol-2-yl)benzyloxy)ethyl]-2-[3-(4-methylphenyl)-2-propynyloxy]ethanamine (600 mg) is dissolved in a solution of CH2Cl2 (10 ml) and EtOH (10 ml) and is treated with a solution of EtOH/HCl until acidic by pH paper. The solution is concentrated in vacuo, then purified by column chromatography using 5% MeOH/CH2Cl2. The residue is isolated, dissolved in methanol and acidified with acidic methanol. The solution is concentrated to obtain N-[2-(4-(benzoxazol-2-yl)benzyloxy)ethyl]-2-[3-(4-methylphenyl)prop-2-ynyloxy]ethanamine hydrochloride (m.p. 161°-162° C.).
