Cyclohex-1-enylphenyl ketone (9.7 g) was slowly added to a concentrated H2SO4 solution (100 ml) at room temperature and the resulting mixture was placed into a pre-heated oil bath (110° C.) for 20 minutes. The hot mixture was poured into ice-water (400 ml) and extracted with CH2Cl2 (4×40 ml). The organic phase was washed with 5% NaHCO3 solution (2×30 ml) and water (30 ml). After drying over Na2SO4 and evaporation the yield was 9.6 g.
