A 125 mg (0.3 mmol) portion of the prostaglandin E1 analogue of Example 3 (14-Phenyl-11α,15R-dihydroxy-9-oxoprost-10,13E-dien-1-oic acid) was stirred into 10 ml of acetic acid-water (2:1) at 50° C. under an inert atmosphere. Progress of the reaction was followed by thin layer chromatography. After 48 hours, the reaction mixture was extracted with ether. Ether layers obtained were combined and washed to neutrality with brine. Removal of the solvent yielded a yellow oil. The oil was azeotroped with toluene and chromatographed on 70 g SG-60, and eluted with benzene-ethanol (19:1) to yield 102 mg of the PGA1 analogue.
