Diazomethane → Benzoic acid, 3-fluoro-, methyl ester

Participants

Reaction Steps

To an ice-cooled and stirred solution of m-fluorobenzoic acid (8.0 g, 57 mmol) in 50 ml of ether was added an excess solution of diazomethane in ether. After concentration, the residue was distilled under reduced pressure to give a colorless transparent oil of methyl m-fluorobenzoate (7.4 g, 48.1 mmol, yield 84.4%, b.p. 80°-82° C./16 mmHg), which was assigned the structure by the following data:
