To a solution of 1,2-difluoro-4-nitrobenzene (1.59 g, 10 mmol) in DMSO (15 mL) were added K2CO3 (3.04 g, 22 mmol) and pyrrole (0.74 g, 11 mmol) with stirring. The reaction mixture was heated at 90° C. for 18 h, and cooled to rt. The mixture was diluted with water (50 mL), filtered and the filter cake was dried to give the title compound as a yellow solid (2.00 g, 97%).
