실험 절차

The title compound was prepared from 4-chloro-3-(thiazol-2-yl)thiophen-2-amine (0.4 mmol) and 2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetic acid (165 mg, 0.8 mmol) according to protocol A. The crude product was purified by column chromatography (4% methanol/methylene chloride) and HPLC to afford N-(4-chloro-3-(thiazol-2-yl)thiophen-2-yl)-2-(2-oxo-3,4-dihydro-1,5-naphthyridin-1(2H)-yl)acetamide (2.1 mg) as a white solid. LCMS m/z of 405.1/407.1 and retention of 3.670 min using the [7] LCMS method. 1H-NMR (300 MHz, CDCl3) δ 8.36 (d, J=4.9 Hz, 1H), 7.71 (d, J=3.4 Hz, 1H), 7.57 (d, J=8.1 Hz, 1H), 7.42 (dd, J=8.1, 5.1 Hz, 1H), 7.36 (d, J=3.4, 1H), 6.82 (s, 1H), 4.92 (s, 2H), 3.44 (t, J=7.1 Hz, 2H), 3.01 (t, J=7.1 Hz, 2H).
