Versuchsvorschrift
4-Fluoro-aniline (1.11 g, 10.0 mmol), cyano-ketone (Example 32) (1.25 g, 10.2 mmol), calcium chloride (1.5 g, 13.5 mmol) and T.H.F. (20 ml) were heated under reflux for 17 hours. After cooling, the mixture was filtered and the solvent evaporated. Kugelrohr distillation (135° C., 0.08 mmHg) gave the product as a pale yellow powder.
