Procedure
A solution of 0.48 g (2.0 mmol) of the intermediate from Example 1, Step C and 0.21 g (2.0 mmol) 4-vinylpyridine in 6 ml acetonitrile were heated at 80° C. over night. The solvent was removed under reduced pressure, and the remaining solid title compound was purified by stirring several times with tert.-butylmethylether, filtered with suction, and dried in vacuo.
