Reaction Steps

Into a solution of 25.6 grams (0.2 mole) of acetone t-butylhydrazone and 20.3 grams (0.2 mole) of triethylamine in 200 ml of pentane, cooled to 5° C in a 500 ml 4-neck round bottom flask equipped with a mechanical stirrer and thermometer, was added 31.9 grams (0.2 mole) of bromine from an addition funnel. After the addition was complete the reaction was stirred an additional 1/2 hour at 5° C, filtered to remove the triethylamine hydrobromide and the pentane evaporated from the filtrate under reduced pressure. The residue was an orange yellow liquid weighing 40 grams (96.6% crude yield). The infrared spectrum of the residue was in agreement with the structure of 2-t-butylazo-2-bromopropane.
