Reaction Conditions

Reaction Steps

In a 50 mL volume glass flask equipped with a stirrer, a thermometer, a dropping funnel and a reflux condenser were placed 1.02 g (5.49 mmol) of methyl 4-hydroxy-3-methoxybenzoate (purity: 98 wt. %), 2.12 g (13.2 mmol) of 3-bromo-1-chloropropane (purity: 98 wt. %), 1.16 g (8.24 mmol) of potassium carbonate (purity: 98 wt. %), and 30 mL of methanol. The resulting mixture was under stirring at 62-67° C. in an argon gas atmosphere for 10 hours. After the reaction was complete, the reaction mixture was filtered. Analysis of the filtrate by high performance liquid chromatography (absolute quantitative analysis) indicated that 1.23 g (reaction yield: 86.5%) of methyl 4-(3-chloropropoxy)-3-methoxybenzoate was produced.
