| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | HCID 21942480 | HCID 21942480 | 21.4% |
Reaction Steps
To a solution of 3-(5-fluoro-pyrid-2-yl)-5-[3-fluoro-5-(1H-tetraazol -5-yl)-phenyl]-1,2,4-oxadiazole (30mg, 0.092 mmol) in tetrahydrofuran (1 mL), 0.5 M diazomethane (1 mL, 0.5 mmol, ether) was added. The reaction was quenched with water and extracted with dichloromethane. The product was purified by column chromatography with 20% ethyl acetate in hexanes to give 6.7 mg (21.4%) of 5-[3-fluoro -5-(1-methyl-1H-tetraazol-5-yl)-phenyl]-3-(5-fluoro-pyrid-2-yl)-1,2,4-oxadiazole. 1H-NMR (CDCl3), δ (ppm): 8.87 (s, 1H), 8.70 (d, 1H), 8.29 (dd, 1H), 8.10 (m, 2H), 7.62 (dt, 1H), 4.46 (s, 3H).
