Reaction Steps

To a stirred solution of 9.75 grams (0.15 moles) of sodium azide in 100 mls of 70% aqueous methanol in a 250 ml erlenmeyer flask cooled in an ice bath, was added 18.85 grams (0.1 moles) of 1-isopropylazo-1-chlorocyclohexane (from Example 3-2) over 15 minutes while holding the reaction temperature below 10° C. After the addition was complete the mixture was stirred an additional 20 minutes at room temperature, poured into 200 ml water and extracted into 100 ml of pentane. The pentane solution was washed successively with 50 ml portions of water and saturated sodium bicarbonate solution, dried over anhydrous sodium sulfate, filtered and the pentane evaporated under reduced pressure on a rotating evaporator. The product was a yellow liquid and weighed 18.4 grams (94.4 % crude yield). It was not shock sensitive and its infrared spectrum was in agreement with the structure of 1-isopropylazo-1-azidocylohexane (strong azide band at 2100 cm-1).
