실험 절차
Benzyl bromide (0.6 mL, 5.04 mmol) was added dropwise to a mixture of 2-chloro-5-nitro-phenol (800 mg, 4.61 mmol) and potassium carbonate (1.27 g, 9.22 mmol) in acetone (20 mL) at room temperature and heated at reflux for 2 h. Inorganic salts were filtered off and washed with acetone (20 mL). The combined filtrate and washings were concentrated in vacuo, the resulting residue then being dissolved in ethyl acetate (25 mL) and washed successively with water (2×20 mL), brine (20 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to yield 2-benzyloxy-1-chloro-4-nitro-benzene (1.20 g, 99%) as a cream solid.
