A mixture of 1-(3-phenoxy-5-(pyridin-2-ylthio)pyridin-2-yl)thiourea (0.075 g, 0.21 mmol), triethylamine (0.073 mL, 0.53 mmol), and 1-(1-acetylpiperidin-4-yl)-2-bromoethanone (0.087 g, 0.26 mmol) was refluxed in Ethanol (10 mL) for 3 hours. The reaction was concentrated and the residue was purified by silica gel (1% MeOH in CH2Cl2) to provide 1-(4-(2-(3-phenoxy-5-(pyridin-2-ylthio)pyridin-2-ylamino)thiazol-4-yl)piperidin-1-yl)ethanone dihydrochloride (0.093 g, 76.2% yield) after HCl salt formation. 1H NMR (d6-DMSO) δ 8.38 (m, 1H), 8.29 (d, 1H), 7.67 (dt, 1H), 7.45-7.37 (m, 3H), 7.21-7.08 (m, 5H), 6.78 (s, 1H), 4.32 (d, 1H), 3.87 (d, 1H), 3.13 (t, 1H), 2.87 (m, 1H), 2.64 (t, 1H), 2.01 (s, 3H), 1.95 (m, 2H), 1.63-1.39 (m, 2H).
