실험 절차
2,5-Difluoro-3-nitrobenzoic acid (2.00 g, 9.847 mmol) was dissolved in MeOH (60 mL). TMSCl (6.220 mL, 49.24 mmol) was added, and the reaction mixture was stirred at reflux for 4 hours. The reaction mixture was concentrated to about 20 mL, and the crystals produced were filtered and dried under high vacuum providing methyl 2,5-difluoro-3-nitrobenzoate (1.55 g, 72.4%) as a crystalline solid.
