This analog was made from 4-methyl-2-(2-(quinoxalin-5-yl)acetamido)thiophene-3-carboxamide using protocol D except that the DMF was also used in the DMA-DMA step with heating to 95° C. (rather than 110° C.) and the hydrazine step was heated at 95° C. (rather than 90° C.). Method[7], MS(ESI) 365.1 [M+H], Retention time=3.58 min; 1H-NMR (300 MHz, CDCl3) δ 11.9 (s, 1H), 8.87 (s, 2H), 8.17-8.14 (m, 1H), 7.92-7.83 (m, 2H), 6.50 (s, 1H), 4.53 (s, 2H), 2.45 (s, 3H), 2.30 (s, 3H).
