Reaction Steps

A mixture of 4.08 g. (0.1 mol.) of 3-[4-(1,1-dimethylheptyl)-2-hydroxyphenyl]-4-methyl-cyclohex-3-enone ethylene ketal, 50 ml. of 2 N oxalic acid and 50 ml. of methanol was stirred at 25° C. for 6 hours. The reaction mixture was added to 500 ml. of water-250 ml. of ether. The ether extract was washed once with 250 ml. of saturated sodium bicarbonate, once with 250 ml. of saturated sodium chloride, dried over magnesium sulfate and evaporated.
