実験手順
25 g (0.65 mol) of sodium amide was introduced into 150 ml of xylene and heated to boiling under agitation. Within one hour, 99 g (0.5 mol) of hydroxymethylcyclododecane, dissolved in 750 ml of xylene, was added dropwise to the boiling suspension. To complete the alcoholate formation the mixture was heated for another two hours under reflux. Thereafter 44 g (0.35 mol) of dimethyl sulfate was added dropwise. The reaction mixture was heated under reflux for another four hours and then poured into a mixture of ice and 35 g of sodium hydroxide. The organic phase was washed with water, dried with Na2SO4, and then distilled.
