Versuchsvorschrift

To a mixture of 2 M trimethylaluminum (0.45 mL, 0.9 mmole, toluene) with toluene (1 mL) at 10° C., trimethylsilyl azide (0.119 mL, 0.9 mmole) was added, followed by the addition of 5-(3-cyano-5-fluorophenyl)-3-(5-fluoro-pyrid-2-yl)-1,2,4-oxadiazole. The reaction was heated at 80° C. for 2 hours and then quenched with 6 N hydrochloride (2 mL) and solid was collected by filtration. The product was recrystallized with dimethylformamide to give 59 mg (36%) of 3-(5-fluoro-pyrid-2-yl)-5-[3-fluoro-5-(1H-tetraazol-5-yl)-phenyl]-1,2,4-oxadiazole. 1H-NMR (DMSO-d 6), δ (ppm): 8.83 (d, 1H), 8.70 (s, 1H), 8.31 (m, 1H), 8.10 (m, 2H), 8.04 (dt, 1H).
