Procedure

Sodium hydride (4.2 mg of a 60% dispersion in mineral oil, 0.107 mmol) was added to a solution of N-(4-bromo-3-(1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetamide (31 mg, 0.0715 mmol) in DMF (0.1 mL) at 0° C. The suspension was stirred for 5 minutes after which iodomethane (12 mg, 0.058 mmol) was added. The reaction mixture was stirred at room temperature for 20 minutes then diluted with water, extracted with ethyl acetate, dried (Na2SO4), filtered, concentrated under vacuum and purified by preparative HPLC to give N-(4-bromo-3-(1-methyl-1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetamide. Retention time (min)=1.740, method [7], MS (ESI) 447.0 (M+H); 1H NMR (300 MHz, CD3OD) δ 8.47 (s, 1H), 8.33 (d, J=5.2 Hz, 1H), 7.85 (bs, 1H), 7.61 (bs, 1H), 7.11 (s, 1H), 4.94 (s, 2H), 4.02 (s, 3H), 3.41-3.36 (m, 2H), 3.01-2.97 (m, 2H).
