Procedure
Combine [5-[1-(3,5-bis-trifluoromethyl-benzyl)-5-phenyl-1H-[1,2,3]triazol-4-yl]-3-(2,2-dimethoxy-ethyl)-isoxazol-4-yl]-(2-chloro-phenyl)-methanone (1 eq) in acetone/H2O (4:1) and p-toluenesulfonic acid (1 eq) with stirring. Attach a reflux condensor and stir overnight in a 60° C. oil bath. Neutralize with saturated aqueous NaHCO3, extract with ethyl acetate, dry over MgSO4, filter, and concentrate under vacuum. 1H NMR (CDCl3): δ 9.84 (s, 1H), 7.83 (s, 1H), 7.56-7.09 (m, 11H), 5.43 (s, 2H), 4.09 (s, 2H).
