Reaction Conditions

Reaction Steps

In a 100 mL volume glass flask equipped with a stirrer, a thermometer and a reflux condenser were placed 10.2 g (54.9 mmol) of methyl 4-hydroxy-3-methoxybenzoate (purity: 98 wt. %), 12.5 g (71.4 mmol) of 4-bromo-1-chlorobutane, 8.3 g (60.4 mmol) of potassium carbonate (purity: 98 wt. %), and 300 mL of acetonitrile. The resulting mixture was refluxed under stirring at 80-85° C. for 8 hours in an argon gas atmosphere. After the reaction was complete, the reaction mixture was filtered and concentrated under reduced pressure. The concentrate was purified by silica gel column chromatography (gel: Wako gel C-200, eluent: n-hexane), to give 13.6 g (isolated yield: 90.0%, purity: 99% in terms of area percentage by high performance liquid chromatography) of methyl 4-(4-chlorobutoxy)-3-methoxybenzoate as a colorless liquid.
