150 mg (0.43 mmol) of the compound from Example 38A were initially charged in 3 ml of dichloromethane, and 63 μl (103 mg, 0.87 mmol) of thionyl chloride were added. The reaction mixture was stirred under RF for 2 h, concentrated under reduced pressure, and then three times toluene was added and the mixture was in each case concentrated again under reduced pressure.
