Participants

Reaction Steps

2.6 ml (2.6 mmol) of a 1 molar tetrabutylammonium fluoride solution in tetrahydrofuran are added to 1.3 g (2.6 mmol) of the compound from Example 65 dissolved in 20 ml of absolute tetrahydrofuran and the mixture is stirred for 1 hour at room temperature. Saturated sodium hydrogen carbonate solution is added to the mixture and it is extracted several times using dichloromethane. The organic phase is dried over magnesium sulphate and concentrated in vacuo, and the residue is chromatographed on a column (silica gel 70-230 mesh, using ethyl acetate/petroleum ether 1:9) as eluent).
