反应详情

A mixture of 35.5 g (115.2 mmol) 2-bromo-5-nitro-O-benzylphenol, 26.3 g (190 mmol) potassium carbonate, 15 mL (127 mmol) benzyl mercaptan, and 200 mL DMF were stirred at room temperature 18 h. TLC analysis indicated a complete reaction, so the thick reaction mixture was transferred to a 2 L Erlenmeyer containing 1 L water and the resulting mixture was stirred in a ice/water bath 30 min. The precipitate was filtered, washed with three 300 mL portions of water, dried at 40° C. 18 h under vacuum to give 2-benzyloxy-4-nitro-S-benzylthiophenol 40.5 g (115.2 mmol, 100%) as a yellow solid.
