Reaction Steps

2-(2,6-Difluoro-3-nitrophenyl)pyridine (1.00 g, 4.29 mmol), ethylamine (2.24 mL, 4.29 mmol) and then DIPEA (0.75 mL, 4.29 mmol) were added to acetonitrile (10 mL) and the resultant mixture stirred at 20° C. for 40 hours under a nitrogen atmosphere. The mixture was concentrated in vacuo and the residue was purified by silica gel chromatography (Si—PPC, gradient 0-50% EtOAc/cyclohexane) to give the title compound as yellow oil (1.00 g, 90%). 1H NMR (CDCl3) δ: 8.73 (1H, ddd, J=6.6, 2.4, 1.3 Hz), 8.28 (1H, dd, J=12.6, 8.1 Hz), 7.80 (1H, td, J=10.3, 2.4 Hz), 7.45 (1H, dq, J=10.4, 1.6 Hz), 7.33 (1H, ddd, J=10.1, 6.5, 1.6 Hz), 6.51 (1H, dd, J=12.7, 10.9 Hz), 2.54-2.44 (2H, m), 1.03 (3H, t, J=9.6 Hz)
