Reaction Steps
2.2 g (8 mmol), obtained in Example 59 (a), of acetoxy-1-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)ethane, dissolved in 20 ml of methanol, are treated with 1.6 g of sodium hydroxide and left stirring for 24 h at room temperature. After evaporation and acidification with 1N HCl, the precipitate is extracted with ethyl ether to yield 1.75 g (93%) of the expected alcohol, melting point 61°-2° C. (αD =-27.2°; c=1, ethanol).
