Reaction Steps

To a cold (0° C.) solution of 1.0 mmol of 4-amino-7-(4-hydroxybutyl)-5-fluoro-1-isobutyl-2-(2-diethylphosphono-5-furanyl)benzimidazole in 20 mL of CH2Cl2 was added 3.0 nimol of PPh3 and 3.0 mmol of CBr4. After 40 min. at rt solvent was removed and the residue was subjected to chromatography to give 4-amino-7-(4-bromobutyl)-5-fluoro-1-isobutyl-2-(2-diethylphosphono-5-furanyl)benzimidazole. CCl4 gave the corrosponding chloro compound.
