실험 절차

A solution of 18.8 grams (0.100 mole) of 2-ethyl-5-(4-methylphenyl)-1,2,3,4-tetraazole in 156 mL of carbon tetrachloride was stirred, and 19.6 grams (0.110 mole) of N-bromosuccinimide, followed by 0.24 gram (0.001 mole) of benzoyl peroxide were added. Upon completion of addition, the reaction mixture was heated to reflux where it stirred for 90 minutes. After this time the reaction mixture was cooled and filtered. The filtrate was concentrated under reduced pressure, yielding 27.7 grams of the subject compound. The NMR spectrum was consistent with the proposed structure.
