実験手順

The preparation of the title compound takes place in analogy to the synthesis of the compound from Example 27A starting with the compound from Example 22A and the compound from Example 35A. 3.5 equivalents of N,N-diisopropylethylamine are used. During the reaction, the product precipitates. The precipitate is collected by suction filtration, washed with tetrahydrofuran and dried under high vacuum. 1.17 g (100% of theory) of the title compound are obtained.
