Reaction Steps

4-[(3-Benzyloxycarbonylpropoxy)carbonyloxymethyl]-1-[(2R,3R)-2-(2,4-difluorophenyl)-2-hydroxy-3-[2-oxo-3-[4-(1H-tetrazol-1-yl)phenyl]-1-imidazolidinyl]butyl]-1H-1,2,4-triazolium chloride (Compound 29, 155 mg) was dissolved in methanol (6 ml). To the solution were added 1N hydrochloric acid solution (0.2 ml) and 10% palladium-carbon (50% wet, 77 mg). The mixture was stirred for 0.5 hours at room temperature under a hydrogen atmosphere. The catalyst was filtered off, and to the filtrate was added distilled water. The mixture was concentrated under reduced pressure, and the concentrate was lyophilized to give 1-[(2R,3R)-2-(2,4-difluorophenyl)-2-hydroxy-3-[2-oxo-3-[4-(1H-tetrazol-1-yl)phenyl]-1-imidazolidinyl]butyl]-4-[(3-carboxypropoxy)carbonyloxymethyl]-1H-1,2,4-triazolium chloride (Compound 33, 122 mg) as a white powder.
