Procedure

A mixture of 1-[(1R,2R)-2-(2,4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]-3-[4-(1H-1,2,3-triazol-1-yl)phenyl]-2-imidazolidinone(0.5 g) and chloromethyl pivalate (4.7 g) was stirred for 5 hours at 100° C. After having been cooled, the mixture was diluted with diisopropyl ether (10 ml), and the resulting powder was collected by filtration. The resulting powder was subjected to CHP-20P column chromatography (eluent: water→5% aqueous solution of acetonitrile→30% aqueous solution of acetonitrile→5aqueous solution of tetrahydrofuran→10% aqueous solution of tetrahydrofuran→20% aqueous solution of tetrahydrofuran) to give 1-[(2R,3R)-2-(2,4-difluorophenyl)-2-hydroxy-3-[2-oxo-3-[4-[3-(2,2-dimethylpropanoyloxy)methyl-1(1H)-1,2,3-triazolio]phenyl]-1-imidazolidinyl]butyl]-4-[(2,2-dimethylpropanoyloxy)methyl]-1H-1,2,4-triazolium dichloride (Compound 8, 134 mg) as a white powder and Compound 1 (141 mg) as a white powder.
