Procedure

To 2,3-difluoro-4-methylphenol (1 g, 6.94 mmol) in dichloromethane at 0° C. was added nitric acid 70% (0.7 mL, 7.77 mmol). After 1 h at room temperature the solution was washed with water, dried and evaporated to give 2,3-difluoro-4-methyl-6-nitrophenol (1.2 g, 6.35 mmol, 91% yield) (D44) as yellow solid.
