Reaction Steps

A mixture of methyl 2,4-dihydroxybenzoate (5.04 g, 30 mmol), 1-bromo-2-fluoroethane (4.18 g, 2.46 mL, 33 mmol), potassium carbonate (4.55 g, 33 mmol) and potassium iodide (1 g) in DMF (20 mL) was heated overnight at 55-60° C. before it was poured into water (150 mL). The resulting white precipitate was filtered, redissolved in dichloromethane, dried (MgSO4), concentrated and diluted with hexane to afford the ether in two crops (1.30 g and 2.19 g). The first crop was characterized:
