실험 절차

A mixture of N-[6-(4-biphenyloxy)hexyl]phthalimide (17 g), ethanol (500 ml) and hydrazine hydrate (10 ml) was heated at reflux for 16 hours, cooled to room temperature, filtered, and evaporated to dryness. The remaining material was stirred with dichloromethane (500 ml), filtered and evaporated to dryness. The crude product was chromatographed on silica gel, eluting with 95:5 dichloromethane:methanolic ammonia, yielding 6-(4-biphenyloxy)-1-aminohexane as an oil, which was converted to the hydrochloride salt, (m.p. 201°-202° C.), according to the method of Example 3.
