Reaction Steps

A mixture of (E)-2-fluoro-5-(3-(2-isobutoxyphenyl)-3-oxoprop-1-enyl)benzonitrile (324 mg, 1 mmol), commercially available 2-(1H-benzo[d][1,2,3]triazol-1-yl)acetamide (176 mg, 1 mmol), and NaOH (80 mg) in 5 mL of EtOH was heated to 50° C. for 5 h. The reaction mixture was acidified with conc. HCl, concentrated and purified by preparative HPLC (reverse-phase, acetonitrile/water with 0.01% ammonium acetate) to afford 2-fluoro-5-(6-{2-[(2-methylpropyl)oxy]phenyl}-2-oxo-1,2-dihydropyridin-4-yl)benzonitrile (70 mg, 39%). 1H NMR (400 MHz, CDCl3): δ 7.90-7.80 (m, 2H), 7.78 (d, 1H), 7.46-7.33 (m, 2H), 7.13-7.03 (m, 2H), 6.62 (d, 2H), 3.85 (d, 2H), 2.21-2.14 (m, 1H), 1.06 (d, 6H). MS (EI) for C22H19FN2O2: 363 (MH+).
