Reaction Steps
A mixture consisting of 6.3 parts of 1-octyn-4(RS)-ol, 7.4 parts of phthalic anhydride and 10 parts by volume of pyridine is heated at the reflux temperature for about 3 hours, then allowed to cool for about 16 hours. At the end of that time the mixture is diluted with ether, then is washed with dilute hydrochloric acid. Extraction with dilute sodium hydroxide, followed by acidification of the alkaline extract affords an aqueous solution which is then extracted with ether. The ether extract is dried over anhydrous sodium sulfate, decolorized with activated carbon and stripped of solvent to afford 1-octyn-4(RS)-ol phthalate.
