Reaction Steps

16 g (55.6 mmol) of ethyl 5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthylglyoxylate and 50 ml of ethyl alcohol were introduced into a round-bottomed flask. A solution of 2.5 g (58.5 mmol) of sodium hydroxide in 50 ml of water was added and the mixture was heated at reflux for one hour. The reaction medium was evaporated to dryness, taken up in water and ethyl ether, the aqueous phase decanted off, acidified to pH 1 with concentrated hydrochloric acid, extracted with ethyl ether, the organic phase decanted off, dried over magnesium sulfate and evaporated. 14 g (97%) of 5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthylglyoxylic acid were recovered in the form of a colorless oil.
