Procedure

To a solution of 2-trifluoromethylbenzaldehyde (8,7 g) and 2,4-pentanedione (5,01 g) in trifluoroacetic acid (10 ml) thionylchloride (4 ml) and catalytic amount of water (0,05 ml) were added at room temperature. The solution was stirred over night at 20°? C. The solvent was evaporated and the residue was distilled in vacuo, bp 110° C./1.5 mbar. Yield 5.3 g (41 %).
