Versuchsvorschrift
A solution of [3-(isopropyl-hydrazono)-propyl]-carbamic acid benzyl ester (0.5 g, 1.9 mmol) and 2-[3-(4-fluoro-phenyl)-2-nitro-allyl]-[1,3]dioxolane (0.48 g, 1.9 mmol) in pyridine (20 mL) was stirred at rt for 2 days. The mixture was cooled to rt, concentrated, and the residue purified by FCC to give the title compound.
