Procedure
4-Bromo-aniline (Aldrich Chemicals) (3.5 g, 20 mmol), cyano-ketone (Example 11) (2.2 g, 20 mmol), calcium chloride (2.5 g, 23 mmol) and T.H.F. (30 ml) were heated under reflux for 7 hours. After being allowed to cool, the mixture was filtered and the solvent evaporated. Kugelrohr distillation (150° C., 0.07 mmHg) gave the product as a brown-grey powder.
