Versuchsvorschrift
150 mg of the resulting benzylamine compound was dissolved in 5 ml of ethanol, and 23 mg of hydrazine was added. The mixture was stirred at room temperature for 30 minutes. The precipitate was separated by filtration, and the solvent was evaporated. The residue was distributed between methylene chloride and water. The organic layer was worked up in a customary manner and purified by silica gel column chromatography [Wakogel C-100, 5 g; eluting solvent: hexane/ethyl acetate=10/1→3/1] to give 95 mg (yield 95%) of the captioned compound as a pale yellow crystalline powder, m.p. 65°-66 ° C.
