Reaction Steps

A mixture of 6-chloro-N-(naphthalen-1-ylmethyl)-3-nitropyridin-2-amine (3.21 g, 10.2 mmol), morpholine (2.66 g, 30.6 mmol) and K2CO3 (2.11 g, 15.3 mmol) in DMF (50 mL) was stirred at 80° C. for 1 h. It was cooled to room temperature and poured into water (300 mL). It was extracted with EA (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=1/1 to afford the desired product as a yellow solid (3.56 g, 96%); LC/MS: MS (ES+) m/e 365 (MH+); 1H NMR (300 MHz, DMSO-d6) δ ppm 3.53 (t, J=4.2 Hz, 4H), 3.60 (t, J=4.2 Hz, 4H), 5.19 (d, J=5.7 Hz, 2H), 6.33 (d, J=9.6 Hz, 1H), 7.44-7.61 (m, 4H), 7.85 (d, J=7.5 Hz, 1H), 7.97 (d, J=7.5 Hz, 1H), 8.12 (d, J=9.6 Hz, 1H), 8.21 (d, J=7.5 Hz, 1H), 9.25 (t, J=5.7 Hz, 1H).
