Reaktionsschritte

6-Methoxy-2-naphthaldehyde (1 g, 5.4 mmol) in acetone (5.0 g), with aqueous NaOH (0.25 g of 2.8% NaOH; 3.3 mol %) was stirred for 1 hour at 20° C. followed by 1 hour at reflux. Water (10 g) was added to precipitate the product which was filtered and dried to give 1.2 g (98% of theory) of 4-(6-methoxy-2-naphthyl)-3-buten-2-one. GC showed 99% conversion and 4% of a heavy co-product (95% of butenone).
