実験手順
75.5 g scopine di-(2-thienyl)glycolate are dissolved in 750 ml acetonitrile while heating gently. After the addition of 22 ml of methyl methanesulphonate the mixture is stirred at 55° C. After the reaction has ended about 350 ml solvent distilled off under reduced pressure. The product crystallises out and is filtered off. It is purified by recrystallisation from methanol/acetone.
