反応手順

15 g (0.06 mol) of 5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthylacetic acid, 150 ml of methanol and 1.6 ml of concentrated sulfuric acid were introduced into a round-bottomed flask. The mixture was heated at reflux for 4 hours, the reaction medium evaporated, taken up in water, and extracted with ethyl acetate. The organic phase was decanted off and dried over magnesium sulfate. 15.9 g (99%) of the expected ester of melting point 83°-85° C. were recovered.
