To a solution of 5-[2-(acetylamino)pyridin-4-yl]-3-(4-chlorobenzyl)-4-cyanothiophene-2-carboxamide (0.030 g, 0.073 mmol) in toluene (0.75 mL) was added 1,1-dimethoxy-N,N-dimethylmethanamine (0.0970 mL, 0.730 mmol), and the mixture was stirred at 100° C. for 90 minutes. The mixture was concentrated and the residue was dissolved in acetic acid (0.75 mL). Hydrazine (0.0114 mL, 0.365 mmol) was added and the mixture was stirred at 100° C. for 1 hour. The mixture was concentrated and the residue was treated with water. The precipitate was collected, washed with water and dried in a vacuum oven to yield the title compound (0.016 g, 48%). LCMS: (FA) ES+, 435. 1H NMR (400 MHz, d6-DMSO) δ: 10.76 (s, 1H), 8.77 (s, 1H), 8.54-8.46 (m, 2H), 7.50-7.47 (m, 1H), 7.37-7.26 (m, 4H), 4.63 (s, 2H), 2.12 (s, 3H).
