The title compound was prepared from 4-bromo-3-(thiazol-2-yl)thiophen-2-amine (90 mg, 0.35 mmol) and 2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetic acid (105 mg, 0.52 mmol) according to protocol A. The crude product was purified by HPLC to give N-(4-bromo-3-(thiazol-2-yl)thiophen-2-yl)-2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetamide (24 mg) as a white solid. LCMS m/z 449.0/451.0 and retention of 4.019 min using method [7]. 1H-NMR (300 MHz, CDCl3) δ 8.39 (d, J=5.2 Hz, 1H), 7.76 (d, J=3.3 Hz, 1H), 7.70 (d, J=8.3 Hz, 1H), 7.51 (dd, J=8.4, 5.3 Hz, 1H), 7.34 (d, J=3.4, 1H), 6.94 (s, 1H), 4.09 (s, 2H), 3.49 (t, J=7.2 Hz, 2H), 3.00 (t, J=7.2 Hz, 2H).
