실험 절차

To a solution of 2-fluoro-4-methyl-5-nitropyridine (150 mg, 0.96 mmol) in acetonitrile (5 mL) was added 7-azabicyclo[2.2.1]heptane hydrochloride (153 mg, 1.15 mmol) and triethylamine (335 μL, 2.40 mmol). The reaction was heated at 80° C. for 16 h. The reaction was quenched with water (2 mL) and solvent was evaporated. The residue was dissolved in ethyl acetate (15 mL), washed with 1N HCl (10 mL), dried over MgSO4, filtered and concentrated in vacuo to afford 6-(7-azabicyclo[2.2.1]heptan-7-yl)-4-methylpyridin-3-amine (160 mg, 71% yield) as yellow solid which was used in next step without purification. 1H NMR (400.0 MHz, CDCl3) δ 8.96 (s, 1H), 6.37 (s, 1H), 4.59 (s, 2H), 2.59 (d, J=0.4 Hz, 3H), 1.83-1.80 (m, 4H), 1.61-1.54 (m, 4H).
