実験手順
To a solution of 4-(1-(4-isopropyloxyphenyl)-1-methylethyl)phenol (0.51 g) in carbon tetrachloriode (1.3 ml), a solution prepared by dissolving 0.23 g of tert-butyl hypochlorite in 0.5 ml of carbon tetrachloride was added dropwise with stirring under ice cooling. After 30 minutes, an ice bath was removed, and the mixture was stirred at room temperature for 30 minutes. The reaction solution was poured into water and extracted three times with 5 ml of carbon tetrachloride. Then, the carbon tetrachloride layers were combined, washed with water, dried over anhydrous magnesium sulfate and then concentrated to give a crude product. This crude product was subjected to silica gel column chromatography to give 0.49 g of 4-(1-(4-isopropyloxyphenyl)-1-methylethyl)-2-chlorophenol (yield, 85%).
