반응 단계
To a suspension of 1.0 mmol of 4-nitro-7-vinyl-5-fluoro-1-isobutyl-2-(2-diethylphosphono-5-furanyl)benzimidazole and 0.1 mmol of Pd(OAc)2 in 8 mL of ether was added an ether solution of diazomethane (generated from 3.0 g of 1-methyl-3-nitro-1-nitrosoguanidine) at 0° C. After stirring at room temperature 20 h solvent was removed and the residue chromatographed to give 4-nitro-7-cyclopropyl-5-fluoro-1-isobutyl-2-(2-diethylphosphono-5-furanyl)benzimidazole.
