실험 절차
2.2 g (10 mmol) of 7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-1-naphthalenecarboxylic acid were heated to 180° C. for 5 h with 2.2 g of copper powder in 22 g of quinoline. After cooling, the mixture was diluted with EA, and the copper was filtered off and then washed several times with dil. hydrochloric acid. After concentration of the organic phase in a rotary evaporator and purification by chromatography on silica gel using cyclohexane/EA 6:1, 0.6 g of 3,3-dimethyl-3,4-dihydro-2H-naphthalen-1-one was obtained.
