Reaction Steps

To a stirred solution of 6.57 grams (.04 moles) of sodium benzenesulfinate in 60 ml of 70% aqueous methanol in a 125 ml erlenmeyer flask was added 6.4 grams (0.034 moles) of 1-isopropylazo-1-chlorocyclohexane (from Example 3-2) dropwise over 25 minutes while holding the temperature at 0° to 5° C. with an ice bath. After the addition was complete, the reaction was stirred for 60 minutes at 0° to 5° C., poured into 200 ml cold water and extracted into 100 ml of pentane. The pentane solution was separated, washed with 50 ml of water, 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 5.95 grams (59.5% crude yield). The infrared spectrum of the product was in agreement with the structure of 1-isopropylazo-1-(benzenesulfonyl)-cyclohexane.
