Chlorotrimethylsilane → Methyl 2-Fluoro-5-nitrobenzoate

참여 물질

반응 단계

To a solution of 2-fluoro-5-nitrobenzoic acid 10-1 (5.22 g, 28.2 mmol) in methanol (30 mL) was added chlorotrimethylsilane 10-2 (6.00 g, 1.96 eq.). The reaction mixture was stirred under reflux during 16 h, then cooled down to room temperature, concentrated and the resulting precipitate was filtered off, washed with a small quantity of methanol, then heptane, to provide 4.36 g (78% yield) of 2-fluoro-5-nitro-benzoic acid methyl ester 10-3 as a white powder; m/z=200 (M+H)+.
