Versuchsvorschrift

Carbon tetrachloride(30 ml) was added to 3-Chloro-1-methyl-naphthalene(2.55 g, 14.4 mmol) prepared in Preparation 36-1) and NBS (2.82 g, 15.8 mmol). A small quantity of benzoylperoxide was added as an initiator and the resulting mixture was heated under reflux for 3 hours. The reaction solution was cooled and filtered to remove the insoluble solid. The filtrate was concentrated and subjected to column chromatography(eluent: hexane/ethylacetate=95/5, v/v) to give 3.10 g(12.1 mmol, Yield 84%) of the title compound.
