実験手順
10 g (0.037 mole) bis(2-hydroxy-5-chlorophenyl)-methane and 8.6 g (0.037 mole) 1,11-dichloro-3,6,9-trioxaundecane are dissolved in 100 ml n-BuOH. To this is added 6.5 g 50% aqueous sodium hydroxide. The resulting solution is heated to reflux for 15 hours, acidified with ethereal HCl, and solvent stripped in vacuo. The resulting gum is chromatographed on Neutral Alumina IV, eluting with ether/ethyl acetate. Appropriate fractions are collected, combined and recrystallized from methanol to yield 3.65 g white crystalline solid; m.p. 143.5°-144°. Yield: 23%.
