Procedure

A solution of [3-(isopropyl-hydrazono)-propyl]-carbamic acid benzyl ester (1.0 mg, 3.8 mmol), 2-[3-(4-fluoro-phenyl)-2-nitro-allyl]-[1,3]dioxolane (0.96 mg, 3.8 mmol), and Et3N (1.53 g, 15.2 mmol) in THF (40 mL) was stirred at 60° C. for 3 days. The mixture was cooled to rt, concentrated, and the residue purified by FCC to give the title compound.
