Procedure

4 mmol of the compound prepared in Example 14 are dissolved in 30 ml of dichloromethane cooled in ice. 11.4 mmol of triethylamine are added dropwise, followed by 4 mmol of tosyl chloride dissolved in dichloromethane. The mixture is left stirring for 30 minutes at room temperature. The solvent is then evaporated off and the expected product is obtained after purification by chromatography on a silica column (elution solvent: dichloromethane).
