Procedure
A mixture of 2-(2,6-difluoro-3-nitrophenyl)pyridine (0.85 g, 3.6 mmol), isopropylamine (0.31 mL, 3.6 mmol) and DIPEA (0.63 mL, 3.6 mmol) in acetonitrile (10 mL) was stirred overnight at RT. The mixture was concentrated in vacuo and the resulting residue was purified by chromatography (Si—PPC, gradient 0-50% EtOAc/cyclohexane) to afford the title compound as a yellow oil (0.49 g, 50%). 1H NMR (CDCl3, 400 MHz): δ 8.76 (1H, ddd, J=6.5, 3.7, 2.4 Hz), 8.26 (1H, dd, J=12.7, 8.1 Hz), 7.86 (1H, br s), 7.81 (1H, td, J=10.4, 2.5 Hz), 7.46 (1H, dq, J=10.5, 1.5 Hz), 7.34 (1H, ddd, J=10.2, 6.5, 1.6 Hz), 6.57 (1H, dd, J=12.7, 10.8 Hz), 2.70-2.54 (1H, m), 0.93 (6H, d, J=8.4 Hz)
