Participants

Reaction Steps

5.8 g of 2-bromo-4-fluoro-5-methylsulphonylbenzoic acid are stirred, at room temperature for 12 h, in 20 ml of DMF together with 3.7 ml of methyl iodide and 8.3 g of potassium carbonate. The reaction mixture is then concentrated and 50 ml of water are added to it. The resulting precipitate is filtered off with suction and dried.
