実験手順

A solution of 20 g (0.100 mol) of 65 and 7.5 g (0.150 mol) of potassium hydroxide in 100 ml of water was mixed with a solution of 10 ml (0.160 mol) of methyl iodide in 100 ml of ether. After addition of 1 g of tetrabutylammonium hydrogen sulphate the mixture was stirred overnight at room temperature. The ether phase was separated and the aqueous phase extracted with 3×100 ml of ether. The combined organic phases were dried over magnesium sulphate. Removal of the solvent in vacuo gave a colorless solid, 66. Yield: 17.0 g (0.089 mol, 89%).
