Reaction Steps

To a solution of 4-hydroxy-6-methyl-1-[(5-methylpyrazin-2-yl)methyl]pyridin-2(1H)-one (1.00 g, 4.3 mmol) in glacial acetic acid (10 mL) was added NCS (0.79 g, 5.94 mmol). The reaction mixture stirred at 60° C. for 6 hours. The solvent was removed under reduced pressure and the resulting residue was triturated with ethyl acetate. The desired product was filtered and dried (0.80 g, 69%). 1H NMR (CD3OD, 400 MHz) δ 8.47 (s, 1H), 8.42 (s, 1H), 6.08 (s, 1H), 5.36 (s, 2H), 2.50 (s, 3H), 2.43 (s, 3H); ES-HRMS m/z 266.0691 (M+H calculated for C12H13N3O2Cl requires 266.0691).
