Versuchsvorschrift

To a solution of 2-(5-methyl-1H-1,2,4-triazol-3-yl)-5-phenyl-1,3,4-oxadiazole (1.00 mg, 0.44 mmol) in DMF (3 mL) Cs2CO3 (430 mg, 1.32 mmol), NaI (78 mg, 0.52 mmol) and 2-chloro-4-(chloromethyl)pyridine (78 mg, 0.48 mmol) were added. The reaction was allowed to stir overnight at RT and then diluted with H2O (10 mL), extracted with EtOAc (3×10 mL), 4:1 CHCl3:i-PrOH (5×10 mL), dried with MgSO4 and concentrated. The crude product was purified on a Biotage pre-packed silica gel column (EtOAc:Hexane 12% to 100% EtOAc) to afford 2-(1-((2-chloropyridin-4-yl)methyl)-5-methyl-1H-1,2,4-triazol-3-yl)-5-phenyl-1,3,4-oxadiazole (88 mg, 57%) as an off-white powder. MS (ES+) C17H13ClN6O requires: 352 found: 353 [M+H]+.
