Participants

Reaction Steps

To (4-(1-(4-(perfluoroethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)methanol (2.00 g, 5.19 mmol) in tetrahydrofuran (25 mL) was added diphenylphosphoryl azide (1.30 g, 5.71 mmol), followed by dropwise addition of 1,8-diazabicycloundec-7-ene (0.861 mL, 5.71 mmol). The mixture was stirred at room temperature for 6 hours. The mixture was diluted with water and ethyl acetate. The organic phase was separated and rinsed with brine, dried over magnesium sulfate, and concentrated to provide the title compound as a yellow solid (1.85 g, 83%): ESIMS m/z 411 ([M+H]+).
