Reaction Steps

To a stirred solution of 2-ethyl-1-[1-(4-fluorobenzyl)-1H-1,2,4-triazol-5-yl]butan-1-ol (0.459 g, 1.42 mmol) in DMF (10 mL) was added sodium azide (0.277 g, 4.26 mmol) and the mixture was heated to reflux for 3 h. After cooling, the reaction mixture was diluted with H2O and extracted with EtOAc twice. The organic extracts were dried (MgSO4), filtered, concentrated in vacuo and purified by column chromatography (SiO2, EtOAc/hexane, 1:9) to yield a clear oil in 67% yield.
