Reaction Steps

A mixture of 2,6-dichloro-3-nitropyridine (3.86 g, 20 mmol), (2,3-dichlorocyclohexa-1,3-dienyl)methanamine (3.52 g, 20 mmol) and K2CO3 (4.14 g, 30 mmol) in DMF (100 mL) was stirred at 80° C. for 3 h. It was cooled to room temperature and poured into water (500 mL). It was extracted with EtOAc (300 mL×2). The combined organic layers were washed with brine (300 mL×3), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by chromatography on silica gel eluted with EtOAc/Pet Ether=1/6 to afford the desired product as a yellow solid (3.37 g, 51%); LC/MS: MS (ES+) m/e 332 (MH+); 1H NMR (300 MHz, DMSO-d6) δ ppm 4.82 (d, J=5.7 Hz, 2H), 6.84 (dd, J=0.9, 6.6 Hz, 1H), 7.28-7.34 (m, 2H), 7.55 (dd, J=2.1, 6.6 Hz, 1H), 8.48 (dd, J=0.9, 6.6 Hz, 1H), 9.22 (t, J=5.7 Hz, 1H).
