Temperature: 70 °C

Procedure

4-[4-(1H-1,2,3-Triazol-1-yl)butyl]phenol (400 mg, 1.84 mmol) and 4-(chloromethyl)-2-[(E)-2-[4-(trifluoromethyl)phenyl]ethenyl]-1,3-oxazole (529 mg, 1.84 mmol) were dissolved in dimethylformamide (3 ml), potassium carbonate (279 mg, 2.02 mmol) was added and the mixture was stirred at 65-75° C. for 4 hours. 4-[4-(1H-1,2,3-Triazol-1-yl)butyl]phenol (40 mg, 0.184 mmol) was added and the mixture was stirred at 65-75° C. for 3 more hours. After cooling to room temperature, water (5 ml) and methanol (3 ml) were added in this order, and the mixture was stirred at room temperature for 40 min. The precipitated crystals were collected by filtration, washed with water and dried under reduced pressure to give 1-[4-[4-[[2-[(E)-2-[-4-(trifiuoromethyl)phenyl]ethenyl]-1,3-oxazol-4-yl]methoxy]phenyl]butyl]-1H-1,2,3-triazole (799 mg, yield 93%).
