Reaction Steps

A solution of 20.0 grams (0.125 mole) of 5-(4-methylphenyl)-1,2,3,4-tetraazole in 230 mL of acetonitrile was stirred and 48.7 grams (0.312 mole) of iodoethane, followed by 17.3 grams (0.125 mole) of potassium carbonate were added. Upon completion of addition, the reaction mixture was warmed to reflux, where it stirred for two hours. After this time, the reaction mixture was concentrated under reduced pressure to a residue. The residue was taken up in ethyl acetate and filtered. The filtrate was concentrated under reduced pressure to a residue. The residue was purified with column chromatography on silica gel using 1:4 ethyl acetate:hexane as an eluant. The appropriate fractions were combined and concentrated under reduced pressure, yielding 18.8 grams of the subject compound. The NMR spectrum was consistent with the proposed structure.
