Procedure

25.3 mmol of bromotrimethylsilane are added to a suspension of the compound obtained in Example 1 (2.53 mmol) in 30 ml of anhydrous acetonitrile. Stirring is carried out at reflux for 1 hour, followed by evaporation to dryness. The residue is dried in vacuo and taken up in methanol. The suspension is stirred for 30 minutes and becomes increasingly thick. The precipitate is filtered off and rinsed with a small amount of methanol to obtain the title product.
