実験手順

2-Fluoro-4-methyl-3-(1H-pyrrol-1-yl)pyridine (3.9 g, 22.1 mmol) was dissolved in 80 mL of ammonia solution (7N in MeOH) in a sealed tube (350 mL). The mixture was heated at 150° C. for 2 days protected with a blast shield. The mixture was cooled to room temperature, then cooled in the ice for minutes. The filtrate was evaporated to dryness and purified by flash chromatography (EtOAc/Hexanes=1:1, Rf=0.5) to give 2.9 g (76%) white solid. 1H NMR (400 MHz, CDCl3) δ 7.96 (d, J=5.1 Hz, 1H) 6.67 (t, J=2.1 Hz, 2H), 6.60 (d, J=5.2 Hz, 1H), 6.41 (t, J=2.1 Hz, 2H), 4.52 (s, 2H), 2.02 (s, 3H). 13C NMR (101 MHz, CDCl3) δ 156.1, 147.2, 145.9, 121.5, 121.1, 116.0, 110.0, 16.7.
