Reaction Steps
Carbon tetrabromide (0.62 g) and triphenylphosphine (0.49 g) were added to a solution of (1S)-1,5-anhydro-2,3,4,6-tetra-O-benzyl-1-[5-(hydroxymethyl)-2-methylphenyl]-D-glucitol (1.0 g) in methylene chloride (10 ml) at room temperature and the mixture was stirred for one hour. The reaction mixture was concentrated and the residue was purified by silica gel column chromatography (n-hexane-ethyl acetate) to obtain (1S)-1,5-anhydro-2,3,4,6-tetra-O-benzyl-1-[5-(bromomethyl)-2-methylphenyl]-D-glucitol (0.8 g).
