Procedure

11.35 g (50 mmol) of 2,3-dichloro-4,5-dicyanobenzoquinone are added to a suspension of 19.4 g (50 mmol) of the compound from Example 10 in 1 l of dichloromethane and the mixture is stirred at room temperature for 2 h. It is then washed three times with water, and the organic phase is treated with sodium sulphate and active carbon, filtered and concentrated to dryness. 17.5 g (91% of theory) of colorless solid remain.
