3-Phenoxy-N-(3-(piperidin-4-yl)-1,2,4-thiadiazol-5-yl)-5-(pyridin-2-ylthio)pyridin-2-amine (0.100 g, 0.2162 mmol), 2-(tert-butoxycarbonyl)acetic acid (0.04544 g, 0.2594 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.06216 g, 0.3243 mmol), and N,N-dimethylpyridin-4-amine (0.002641 g, 0.02162 mmol) were dissolved in CH2Cl2 (5 mL). Triethylamine (0.04375 g, 0.4323 mmol) was added and the solution was stirred at ambient temperature for 3 hours. Water was added and the solution was extracted with CH2Cl2, dried, filtered, and concentrated. The residue was purified by silica gel (1-2% MeOH in CH2Cl2) to give the title compound (0.1116 g, 83.30% yield). 1H NMR (d6-DMSO) δ 12.35 (s, 1H), 8.39 (d, 1H), 8.37 (m, 1H), 7.66 (dt, 1H), 7.47 (d, 1H), 7.42 (t, 2H), 7.21-7.11 (m, 5H), 6.73 (t, 1H), 4.29 (t, 1H), 3.81 (m, 3H), 3.20-3.02 (m, 2H), 2.81 (t, 1H), 2.01 (m, 2H), 1.76-1.53 (m, 2H), 1.38 (s, 9H).
