Yield: 75%

Reaction Conditions:

with hydrogenchloride in methanol;hexane

Steps:

2.A Methyl 3-Fluorobenzoate
EXAMPLE 2A Methyl 3-Fluorobenzoate To a solution of anhydrous hydrochloric acid (10.5 g) in anhydrous methanol (100 ml) is added m-fluorobenzoic acid (13.3 g.; 0.095 mole). The reaction mixture is stirred at room temperature overnight. The solvent and anhydrous hydrochloric acid are then removed under vacuum and the residue slurried with hexane (100 ml). The hexane insoluble layer is decanted and the hexane solution water washed (2*100 ml) before drying with anhydrous magnesium sulfate. The hexane filtrate is then concentrated under vacuum to afford 11.0 g (75% yield) of methyl 3-fluorobenzoate as a yellow liquid. Elemental anal. calcd. for C₈ H₇ FO₂: C, 62.35; H, 4.57; F, 12.33. Found: C, 62.52; H, 4.70; F, 11.89.
