Reaction Steps

To a stirred solution of 1,2,4-triazole (0.803 g, 11.6 mmol) in THF (100 mL) at 0° C. was added 4-fluorobenzyl bromide (2.0 g, 10.6 mmol), then 1,8-diazabicyclo[5.4.0]undec-7-ene (1.9 mL, 12.7 mmol) and the mixture was slowly warmed to room temperature. The solution was concentrated in vacuo, then purified by column chromatography (SiO2, MeOH/EtOAc, 5:95) to yield a white solid in 68% yield.
