Combined N-benzyl-6-hydrazinylnicotinamide (30 mg, 0.124 mmol), methyl 2-(4-cyano-3-fluorophenyl)-3-(dimethylamino)acrylate (40.0 mg, 0.161 mmol) and acetic acid (0.021 mL, 0.371 mmol) in 2-propanol (1.0 mL) and stirred at 20° C. for 28 h. Then Hunig's base (0.130 mL, 0.743 mmol) was added and the reaction mixture was heated at 50° C. for 15 h. The reaction mixture was diluted with DMSO (0.1 mL) and purified by prep HPLC to give the title compound (22 mg, 43.0% yield) as a peach solid. 1H NMR (400 MHz, DMSO-d6) 6 ppm 4.53 (d, J=5.8 Hz, 2H) 7.21-7.30 (m, 1H) 7.31-7.39 (m, 4H) 7.85 (t, J=7.7 Hz, 1H) 7.99 (d, J=8.3 Hz, 1H) 8.10 (d, J=11.9 Hz, 1H) 8.42-8.58 (m, 2H) 8.74 (br. s., 1H) 8.97 (d, J=1.5 Hz, 1H) 9.27 (t, J=5.9 Hz, 1H) 13.81 (br. s., 1H).
