To a solution of 6-phenyl-1-hexyl iodide (0.63 g; 2.2 mmol) in THF (12 ml) is added 2-[4-(benzoxazol-2-yl)benzyloxy]ethylamine hydrochloride (0.6 g ; 2 mmol) followed by NaH (60% suspension; 0.11 g). The reaction mixture is stirred for 1 hour at room temperature and then heated for 1 1/2 hours at reflux. The mixture is next cooled, acidified with HCl/EtOH, concentrated and purified by column chromatography using 10% MeOH/CH2Cl2 as eluant. The resultant product is treated with HCl/EtOH and recrystallized from EtOH to give pure N-[2-(4-(benzoxazol-2-yl)benzyloxy)ethyl]-6-phenyl-1-hexanamine hydrochloride. (m.p. 163°-165° C.).
