1.5 mmol of the compound prepared in Example 1 is dissolved in 10 ml of dimethylformamide in the presence of 4.4 mmol of 1-iodopropane and 4.4 mmol of potassium carbonate. After 24 hours, stirring at 60° C., the solvent is evaporated off and the crude reaction mixture is taken up with 10 ml of water and extracted with dichloromethane. The organic phase is dried and evaporated and the expected product is obtained after purification by chromatography on a silica column (elution solvent: ether/petroleun ether, 1:99).
