Procedure

The product obtained in Step A (18 mmol) is added all at once to 5 ml of sulphuric acid (d=1.81). The temperature of the reaction mixture rises rapidly to approximately 80° C. After stirring for 5 minutes, the mixture is poured into 100 ml of ice-cold water and is then extracted with dichloromethane. The organic phase is then washed with water, then with saturated sodium hydrogen carbonate solution and then again with water. The organic phase is then dried over magnesium sulphate and is then concentrated under reduced pressure. The residue is chromatographed to yield the title product.
