Procedure

4.89 g (15.557 mmol) of the compound from Example 32A were reacted analogously to the procedure of Example 28A with 4.391 g (23.336 mmol) of dimethyl 2,2-dimethyl-3-oxobutanedioate (described in J. Am. Chem. Soc. 124(14), 3680-3691; 2002). After the reaction had gone to completion, a solid was filtered off, which was washed with ethanol and then dried under high vacuum. This gave 6.04 g (85% of theory) of the title compound.
