Water → N-[8-(2-naphthyloxy)octyl]phthalimide

Participants

Reaction Steps

1-Chloro-8-(2-naphthyloxy)octane (4.75 g) and potassium phthalimide (4.2 g) were heated in dimethylformamide (25 ml) at 120° for 4 hours. The solution was then cooled, added to water, and extracted with methylene chloride. The extracts were then dried and evaporated to afford N-[8-(2-naphthyloxy)octyl]phthalimide as a gum. This material was refluxed for 16 hours in ethanol (150 ml) containing 85% aqueous hydrazine hydrate (3 ml). The solution was cooled and water (450 ml) and 10% aqueous potassium hydroxide (50 ml) were added. The resultant solution was extracted with hexane; the extract was dried and evaporated to afford the title compound as an oil (hydrochloride mp 169°-170°).
