Reaction Steps

To a solution of sodium hydride (92 mg of a 60% dispersion in mineral oil, 2.3 mmol) in DMF (7 mL) was added ethanethio](0.14 g, 2.2 mmol), followed by a solution of 1-(3-fluorobenzyl)-4-methoxy-2-oxo-1,2-dihydropyridine-3-carbonitrile (0.23 g, 0.89 mmol) in DMF (2 mL), and the reaction mixture was heated to 100° C. The reaction mixture was cooled to room temperature, acidified with 3 N HCl, and washed with EtOAc. The organic solution was washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure to give 1-(3-fluorobenzyl)-4-hydroxy-2-oxo-1,2-dihydro-pyridine-3-carbonitrile as an off-white solid (0.20 g, 91%): 1H NMR (300 MHz, MeOD) δ 8.00 (s, 1H), 7.82 (d, J=8 Hz, 1H), 7.40-7.30 (m, 1H), 7.15-7.00 (m, 2H), 6.13 (d, J=8 Hz, 1H), 5.11 (s, 2H)
