실험 절차

A mixture of 5′-chloro-2′-fluoro-N-(3-fluorobenzyl)-2,4′-bipyridin-6-amine (Intermediate B) (15 mg, 0.045 mmol) was added DMSO (0.4 ml) and methyl amine 40% in water (200 μl, 2.293 mmol) in a microwave tube was microwaved at 145° C. for 900 seconds and the reaction progress was followed by LCMS. Most of the amine was removed under vacuum, 0.5 ml of DMSO was added, filtered and purified by prep LC. After lyapholization 13.9 mg of the title compound was obtained as a TFA salt. LCMS (m/z): 343.0 (MH+), retention time=0.67 min.; 1H NMR (300 MHz, METHANOL-d4, 25° C.) δ ppm 2.97 (s, 3H) 4.62 (s, 2H) 6.81 (d, J=8.50 Hz, 1H) 6.91-7.02 (m, 3H) 7.09 (d, J=9.96 Hz, 1H) 7.17 (d, J=7.62 Hz, 1H) 7.27-7.39 (m, 1H) 7.69 (dd, J=8.50, 7.33 Hz, 1H) 8.03 (s, 1H).
