3-(5-anmino-6{3-[(3S)-piperidin-3-yl]-1H-1,2,4-traiazol-5-yl}pyrazine-2-yl)-N[4-chloro-2-fluorophenyl)methyl]benzamide: 3-(5-Amino-6-cyano-pyrazin-2-yl)-N-(4-chloro-2-fluoro-benzyl)-benzamide (238.0 mg, 0.63 mmol) and 1,1-dimethylethyl (3S)-3-(hydrazinocarbonyl)piperidine-1-carboxylate (460 mg, 1.89 mmol) was combined together and it was heated to 180° C. for 1 or 2 hrs. The reaction mixture was poured into water (575 mL), and extracted with ethyl acetate (2×35 mL) then dried over anhydrous sodium sulfate and filteration, concentration and purified by MPLC to give 3-[5-amino-6-(5-piperidin-3-yl-2H-[1,2,4]triazol-3-yl)-pyrazin-2-yl]-N-(4-chloro-2-fluoro-benzyl)-benzamide (206.0 mg, 65.0% yield): 1H NMR (400 MHz, d4-MeOH): δ 8.60 (d, 2H), 8.20 (d, 1H), 7.82 (d, 1H), 7.58 (t, 1H), 7.38 (t, 1H), 7.15 (m, 2H), 4.60(s, 2H), 3.62 (m, 1H), 3.40(m, 3H), 2.99 (m, 1H), 2.37 (m, 1H), 1.98 (m, 3H); MS (EI) for C25H24N8OFCl: 507.03 (MH+).
