Reaction Steps

2.2 ml of thionyl chloride were added at 15° C to a mixture of 7 g of 2-methyl-2-[p-(4-tetrahydropyranyl)-phenoxy]-propanoic acid, 70 ml of benzene and 3.5 ml of triethylamine and the mixture was stirred for 2 hours at room temperature and was then filtered. The filtrate was slowly added to 250 ml of 5.4N hydrochloric acid in ethanol and the mixture was stirred for 12 hours at room temperature and was then concentrated to dryness. The residue was added to 100 ml of ether and the solution was washed with a saturated sodium bicarbonate solution and then with water. The solution was dried and evaporated to dryness and the oily residue was distilled under reduced pressure to obtain 6.5 g of ethyl 2-methyl-2-[p-(4-tetrahydropyranyl)-phenoxy]-propanoate with a boiling point of 138°-140° C at 0.1 mm Hg.
