Hydrochloric Acid → 6-(4-Acetyl-3-hydroxy-2-propylphenoxy)-2,2-dimethylhexanoic acid

Participants

Reaction Steps

A solution of 1.1 g. of methyl 6-(4-acetyl-3-hydroxy-2-propylphenoxy)-2,2-dimethylhexanoate and 2.6 g. of lithium iodide in 50 ml. of collidine was heated to 100° C. under a nitrogen blanket for about 46 hours. The reaction mixture was then added to ice. After making the solution acidic with hydrochloric acid, the solution was extracted with ether. The ether phase was washed three times with a 10% sodium bicarbonate solution. The ether solution was then further washed with a dilute hydrochloric acid solution, water, and a saturated sodium chloride solution. Evaporating the ether layer to dryness gave 1.03 g. of the title product, M+ =336; NMR.
