実験手順
Reaction: ##STR17## into 1 liter reaction flask equipped with stirrer thermometer reflux condenser and heating mantle is placed 100 ml anhydrous methyl, 1.25 moles (100 grams) of 50% aqueous NOAH solution, 100 ml water and 154 grams (1 mole) of the methyl ester of 4-methyl-cyclohexene-1-carboxylic acid. The reaction mass is stirred for a period of 5 hours at room temperature and then extracted with 1 volume of diethyl ether. The aqueous layer is set aside with 10% hydrochloric acid and extracted with diethyl ether. The diethyl ether extracts are washed with saturated sodium chloride solution and the ether is evaporated yielding 100.5 grams of solid melting at 95° C. This material is the carboxylic acid having the structure: ##STR18## as confirmed by NMR and IR analysis.
