Procedure

A mixture of 3-bromo-2-fluoro-5-nitro-benzaldehyde (1.0 g, 4 mmol), potassium carbonate (667 mg, 4.8 mmol) and 2-methyl-2-propanethiol (326 mg, 0.40 mL, 3.6 mmol) in dry DMF (5 mL) was heated at 110° C. in a sealed tube for 16 h. The reaction was cooled to RT, water was added, and the mixture extracted with dichloromethane (2×30 mL). The combined organic fractions were washed with water (3×15 mL), dried over sodium sulfate, filtered and concentrated to afford 1.2 g of the crude title compound, which was used without further purification.
