Reaction Steps
10.7 grams of ethyl 1-n-butyl-2-hydroxy-cyclopentane carboxylate obtained in Example 16 were diluted with 60 ml of methylene chloride. At room temperature and with magnetic stirring, 6.108 ml of pyridine was slowly added, then 8.876 ml of benzoyl chloride was dropwise added. Upon the completion of the addition, the reaction was continued for 12 hours. Then the procedure as described in Example 23 was followed, to give 19.06 g of brown liquid. The brown liquid was purified through column chromatography to give a liquid with a purity, measured by GC, of 96.03%. Yield: 93.7%. MS: 318(M+), 273(M+—OCH2CH3), 261(M+−CH2CH2CH2CH3), 245(M+—CO2CH2CH3), 213, 197(M+—C6H5CO2), 105(base), 77.
