Procedure

To a solution of 1-[(1R,2R)-2-(2,4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]-3-[4-(1H-tetrazol-1-yl)phenyl]-2-imidazolidinone (1.0 g) in acetonitrile (15 ml) was added (3-benzyloxycarbonylpropyl) iodomethyl carbonate (1.0 g) under a nitrogen atmosphere, and the mixture was stirred for 20 hours at 45-50 C. The reaction mixture was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography (eluent: ethyl acetate→acetone ), and a fraction containing the desired compound was concentrated under reduced pressure. The residue was subjected to ODS column chromatography (eluent: methanol/water=3/2) to give 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 iodide (Compound 32, 1.47 g) as a yellow powder.
