Participants

Reaction Steps

1N Potassium hydroxide solution (10 mL) was added dropwise with stirring to a chilled solution of 5-[[2-(cyclooctyloxy)ethyl]oxy]-alpha-oxo-2-thiopheneacetic acid ethyl ester (4.43 g) in methanol (50 mL). After the reaction was stirred at 0°-5° C. for 15 minutes, the product was isolated as described in Example 6 to furnish 3.9 g of 5-[[2-(cyclooctyloxy)ethyl]oxy]-alpha-oxo-2-thiopheneacetic acid as a yellow-orange oil. Crystallization of the product from wet benzene-hexane furnished 3.1 g of the hydrated acid as a pale yellow crystalline solid, mp 60°-62 ° C.
