Versuchsvorschrift

Using the procedure of Stage 2 of Example 20, 153 mg of the product of Stage 1 of Example 20, 1.5 ml of 1,2-dichlorethane and 0.1 ml of triethylamine were reacted and the solution was placed in an ice-cooled water bath. 1 ml of the product of Example 7 of European Patent Application EP 0,494,819 was added and the mixture was allowed to return to ambient temperature. The reaction medium stood for one hour, was dried and the residue was purified on silica with methylene chloride-methanol: 7-3 as eluant to obtain 277 mg of the expected product (white crystals) melting at 199°-200° C.
