Procedure
At −78° C., a solution of 27 μl (0.203 mmol) of diethylaminosulphur trifluoride (DAST) in 0.5 ml of anhydrous dichloromethane was added to a solution of 100 mg (0.169 mmol) of the compound of Example 148 in 3.5 ml of anhydrous dichloromethane. After the reaction mixture had been stirred at −78° C. for 1 h, 1 ml of saturated aqueous sodium bicarbonate solution was added and the mixture was warmed to RT. Using an Extrelut cartridge NT3 (from Merck, Darmstadt, Germany), the mixture was freed from salts and aqueous components. After concentration, the residue obtained was separated into its components by preparative HPLC (Method 36). Evaporation of the product fractions and drying of the residue under high vacuum gave 50 mg (50% of theory) of the title compound.
