Potassium Carbonate → 3-Chloropropyl 4-(3-chloropropoxy)-2-fluorobenzoate

Participants

Reaction Steps

2-fluoro-4-hydroxybenzoic acid (1 g, 6.41 mmol, 1 eq) is reacted with bromochloropropane (0.82 ml, 8.33 mmol, 1.3 eq) in the presence of potassium carbonate (1.77 g, 12.81 mmol, 2 eq) in methyl ethyl ketone (18 ml) at 80° C. overnight, filtered, washed with acetone and concentrated under vacuum to afford 2 g of 3-chloropropyl 4-(3-chloropropoxy)-2-fluorobenzoate i76.
