4-Methoxycyclohexylmethanol (10.5 g) was dissolved in carbon tetrachloride (45 g) and cooled with ice. Phosphorus tribromide (2.8 ml) was added dropwise to the above solution and stirred at ambient temperature overnight. The carbon tetrachloride layer was decanted and dried over magnesium sulfate. After filtering, the carbon tetrachloride from the filtrate was evaporated to yield pale yellow colored liquid of bromomethyl-4-methoxycyclohexane.
