Procedure

To a solution of N-(4-chloro-3-(1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(2-oxo-1,5-naphthyridin-1(2H)-yl)acetamide (0.047, 0.12 mmol) in DMF (0.4 mL) was added potassium carbonate (0.041 g, 0.30 mmol) and iodomethane (17 uL, 0.27 mmol). After 2 h the reaction mixture was partitioned between H2O and ethyl acetate. The organic phase was collected, dried (sodium sulfate), filtered and concentrated under reduced pressure. The desired product was submitted to prep HPLC for further purification. Retention time (min)=4.407, method [8], MS(ESI) 403.1 (M+H). 1H NMR (CDCl3) δ 12.40 (s, 1H), 8.32 (d, J=5.1 Hz, 1H), 8.07 (s, 1H), 7.56 (d, J=8.1 Hz, 1H) 7.41 (d, J=5.1 Hz, 1H), 7.39 (d, J=5.1 Hz, 1H) 6.81 (s, 1H), 4.89 (s, 2H), 4.02 (s, 3H), 3.47-3.42 (m, 2H), 3.03-2.98 (m, 2H).
