실험 절차

To a stirred solution of 10.45 grams (.071 moles) phthalimide in 80 mls of N,N-dimethylformamide in a 250 ml 4-neck flask equipped with a magnetic stirrer, thermometer and addition funnel was added 4.0 grams (.05 moles) of 50% sodium hydroxide and the solution stirred for 15 minutes at 40° C. To this solution was added dropwise 11.45 grams (.05 moles) of 1-cyclohexylazo-1-chlorocyclohexane (from Example 3-11) over 20 minutes at 40° to 45° C. After the addition was complete, the reaction was stirred an additional 60 minutes at 40° C., poured into 250 ml cold water and the white solid that formed was filtered off and dissolved in 100 ml of pentane. The insolubles were filtered off and the pentane filtrate washed with 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 white solid and weighed 11.5 grams (68% crude yield). The infrared spectrum of the product was in agreement with the structure of 1-cyclohexylazo-1-phthalimidocyclohexane (absence of NH and OH bands and a strong carbonyl band at 1700-1730 cm-1).
