Reaction Steps

To a solution of 0.124 g (0.26 mmol) 1-[4-(4-{2-[2-(4-Trifluoromethoxy-phenyl)-vinyl]-oxazol-4-ylmethoxy}-phenyl)-butyl]-1H-[1,2,3]triazole in 20 ml EtOH 0.973 μl (50 mg/ml in EtOH) of p-toluenesulfonic acid was added and heated to 60° C. for complete dissolution. After evaporation of the solvent the oily residue crystallized slowly to yield 1-[4-(4-{2-[2-(4-Trifluoromethoxy-phenyl)-vinyl]-oxazol-4-ylmethoxy}-phenyl)-butyl]-1H-[1,2,3]triazolium p-toluenesulfonate.
