Reaction Steps

A mixture of imidazole (0.997 g, 14.65 mmol) and tert-BuOK (1.722 g, 15.35 mmol) was put under Ar in a 100 mL and dissolved in dry DMSO (15 mL) to give a colorless solution. After 5 min, 1-fluoro-2-nitro-4-(trifluoromethyl)benzene (2.04 mL, 14.58 mmol) was added within 30 s, immediately leading to a darkening of the rm to black. A temperature rise was also noted. The black solution was stirred at RT for 20 min. Ice water (60 mL) and EtOAc (50 mL) were added, the organic layer was isolated, and the aqueous phase was extracted twice with 20 mL EtOAc. The organic layer was washed with H2O (2×30 mL), brine, dried, filtered and evaporated to give the title compound as an orange oil. Yield: 3.66 g (97%).
