Procedure

4-t-Butylphenol (2.76 g, 18.4 mmol) was dissolved in dichloromethane (25 ml). Sulfuryl chloride (1.6 ml, 9.9 mmol) was added dropwise to the obtained solution, and they were stirred at room temperature for 3 days and then concentrated under reduced pressure. After the purification by the silica gel column chromatography, 2-chloro-4-t-butylphenol (yield: 2.71 g, 80%) was obtained.
