実験手順
Add NBS (5.266 g, 23.9 mmol) and benzoyl peroxide (49 mg, 0.2 mmol) to a solution of 4-bromo-3-chlorotoluene (4.925 g, 23.9 mmol) in carbon tetrachloride (49 mL) and heat overnight at 90° C. Cool to 0° C. and filter the mixture. Concentrate the filtrate in vacuo to obtain the desired intermediate as a yellow oil (5.807 g, 85%).
