Reaktionsschritte

The compound obtained in Step A (21.4 mmol) is dissolved in 120 ml of tetrahydrofuran, and potassium tent-butylate (64.2 mmol) is added in small portions. After stirring for 30 minutes at ambient temperature, the reaction mixture is evaporated to dryness. The residue obtained is taken up in 150 ml of water and the aqueous phase is extracted twice with 60 ml of diethyl ether. The organic phase is washed with water, dried over magnesium sulphate, decolourised on vegetable carbon and evaporated. The residue obtained is purified on silica gel (eluant: petroleum ether) to yield the title product in the form of a yellow oil.
