Reaction Conditions

Reaction Steps

To 5-ethenyl-4-fluoro-2-nitrophenyl methyl ether (1.0 g, 5.1 mmol) in 10 mL of iPrOH was added, piperidine (1.3 g, 15.2 mmol). The mixture was heated to 180° C. 17 min in the microwave. The solvent was rotovaped down and the crude product was purified by flash chromatography to give the title compound of step C (0.81 g, 2.87 mmol, 57%). 1H NMR (400 MHz, CDCl3) δ ppm 7.59 (d, J=8.97 Hz, 1H), 7.01 (d, J=5.86 Hz, 1H), 3.92 (s, 3H), 2.82-2.88 (m, 2H), 2.53-2.58 (m, 2H), 2.40-2.48 (m, 4H), 1.55-1.61 (m, J=5.49, 5.49, 5.49, 5.49 Hz, 4H), 1.40-1.47 (m, 2H).
