Reaction Steps
To a solution of triphenylphosphine (20 g, 75.6 mmol) in anhydrous tetrahydrofuran (165 mL) was added carbon tetrachloride (50 mL). After the mixture was stirred at room temperature for 20 minutes, 7-chloro-3-hydroxymethyl-2-methyl-naphthalen-1-ol (8.4 g, 37.8 mmol) was added as a solid under a nitrogen atmosphere. After being stirred at reflux for 2 hours, the resulting mixture was cooled to room temperature, and concentrated in vacuo. The residue was purified by column chromatography (elution with 5% ethyl acetate in petroleum ether) to afford 7-chloro-3-chloromethyl-2-methyl-naphthalen-1-ol (8.7 g, 96%) as a white solid.
