Procedure
To a solution of 2-chloro-3-nitropyridine (15.4 g, 97.1 mmol) in N,N-dimethylformamide (100 mL) were added 4-chloroaniline (12.4 g, 97.2 mmol) and potassium carbonate (20 g, 140 mmol). The reaction mixture was stirred at 100° C. for 18 hours, and then poured into ice-water (200 mL). The precipitate was collected via filtration and washed with water (3×30 mL) to provide the product as a black solid. Yield: 15 g, 60 mmol, 62%. 1H NMR (400 MHz, DMSO-d6) δ 9.97 (br s, 1H), 8.47-8.57 (m, 2H), 7.69 (d, J=8.8 Hz, 2H), 7.41 (d, J=8.8 Hz, 2H), 7.01 (dd, J=8.2, 4.6 Hz, 1H).
