Reaction Steps

1-[4-[4-[[2-[(E)-2-[4-(Trifluoromethyl)phenyl]ethenyl]-1,3-oxazol-4-yl]methoxy]phenyl]butyl]-1H-1,2,3-triazole (1.0 g) was dissolved in ethyl acetate (50 ml) and tetrahydrofuran (5 ml). A solution of sulfuric acid (209 mg) in tetrahydrofuran (5 ml) was added dropwise. The crystals were precipitated. The mixture was stirred at room temperature for 40 min and filtrated. The mixture was washed with ethyl acetate (3 ml) and dried under reduced pressure (40° C.) to give 1-[4-[4-[[2-[(E)-2-[4-(trifluoromethyl)phenyl]ethenyl]-1,3-oxazol-4-yl]methoxy]-phenyl]butyl]-1H-1,2,3-triazole sulfate (1.13 g, yield 93%).
