2-[3-(4-Chloro-phenoxymethyl)-benzyl]-phthalimide (345 mg, 0.91 mmol) and hydrazine hydrate (0.27 mL, 4.5 mmol) were dissolved in THF (2.5 mL) and EtOH (2.5 mL). The mixture was heated to reflux for 17 h, cooled to r.t. and evaporated to dryness. The residue was suspended in THF (6 mL). The precipitate was filtered and washed with THF (4×3 mL). The filtrate was evaporated to dryness to give the title compound, pure enough for further reactions.
