Vorschrift

1.35 g of 5,7-Difluoro-1-methylnaphthaline in 10 ml of carbon tetrachloride are refluxed for 41/2 hours with 1.4 g of N-bromosuccinimide and 50 mg of dibenzoylperoxide. The cooled mixture is filtered and the solvent removed under vacuum. The purity of the crystalline crude product is sufficient for further reaction, m.p. 74°-76.5°.
