Patent; Dutta, Aloke K.; US2003/195219; (2003); (A1) English View in Reaxys 11 : BBr3 hydrolysis Example 11 BBr3 hydrolysis To a solution of 1.0 mmol of substituted 2-[(5-diethylphosphonate)furanyl]benzimidazole in 3 mL of anhydrous CH2 Cl2 was added 10 mmol of 1.0 M BBr3 solution in CH2 Cl2 at -78° C. and the mixture was allowed to warm to room temperature. After 16 h, solvent and excess BBr3 were removed under reduced pressure and the residue was taken into 3 mL of water. The precipitate was filtered, washed with water, and MeOH and was dried under vaccum at 50° C. The following compound was prepared in this manner: 11.1: 4-Amino-5-hydroxy-1-isobutyl-2-(2-phosphono-5-furanyl) benzimidazole. mp=206-209° C.; Anal.

Stirring was continued for 1.5 h at 0° C., and the solution was then poured onto ice-cold 5percent sodium bicarbonate. The layers were separated and the aqueous layer was extracted with methylene chloride (3*60 mL). The combined organic layers were washed with brine (3*10 mL), dried (Na2 SO4) and evaporated to a colourless foam (322 mg). This was purified by plc (silica gel, acetone:hexane, 1:4) to give three products. The leading band was IV B (25 mg). The middle band was a 79/21 mixture of IV H and IV I (245 mg, 75percent). Separation and characterization of these two compounds is described in the following example.
