Participants

Reaction Steps

A suspension of 880 mg. of ethyl 15-azido-9-oxoprostanoate (Example 110) in 15 ml. of methanol-water (1:1) containing 360 mg. of potassium hydroxide is stirred at ambient temperature for 18 hours. The resulting solution is acidified with dilute hydrochloric acid and the oily layer is taken up in ether. The ether is washed with saturated sodi sodium chloride solution, dried with anhydrous magnesium sulfate and taken to dryness to give 797 mg. (98%) of an oil; λmax. 3.0-3.5 broad (acid group), 4.88 (azido group), 5.78 and 5.90 (carbonyl groups).
