- the reaction at elevated temperature, preferably from 50 ° C to 130 ° C and in particular from 60 to 1 10 ° C. These temperatures are for solution in solution; If, on the other hand, the test is carried out in bulk and the melting point of the compound of the formula 2 is above room temperature, the reaction temperature will of course be at least equal to the temperature of the melt of the reaction mixture.

- compound 1 reacts at least partially to compounds 1 a, 1 b and / or 1 c. It is believed that these intermediates too in the first implementation variant (addition of compound 1 to the compound 2 introduced in alkaline medium) are carried out in situ.
- the workup of the resulting reaction mixtures and the isolation of the compounds of formula 3 is carried out in the usual manner, for example by an extractive workup, by removing the solvent, for.
