実験手順

Added acetic anhydride (0.0169 g, 0.165 mmol) to a mixture of 3-phenoxy-N-(4-(piperidin-4-ylmethyl)thiazol-2-yl)-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-amine dihydrochloride (0.100 g, 0.165 mmol), triethylamine (0.0837 g, 0.827 mmol), and THF (5 mL) at 0° C. Warmed to ambient temperature and stirred for 4 hours. Partitioned between ethyl acetate and 2N NaOH, washed with water, brine, dried, and concentrated. The residue was dissolved in dichloromethane (2 mL) and 1N HCl in ether was added. Diluted in hexanes, and concentrated, added hexanes again and concentrated to afford the title compound ((Mixture of rotamers; 0.092 g, 91.2% yield) as a light yellow powder: 1H NMR (d6-DMSO) δ 8.65 (d, 1H); 8.47 (d, 1H), 8.46 (s, 1H), 7.77 (d, 1H), 7.41 (s, 1H), 7.41 (d, 2H), 7.15-7.20 (m, 4H), 6.84 (s, 1H), 0.95-4.36 (m, 1H), 1.97 (s, 3H).
