실험 절차

To a stirred solution of tert-butyl 4-(6-hydroxybenzo[d]thiazole-2-carboxamido)piperidine-1-carboxylate (0.20 g, 0.54 mmol) in toluene (4 mL) at room temperature was added diisopropyl azodicarboxylate (0.13 g, 0.64 mmol), 1-(4-(trifluoromethyl)phenyl)-piperidin-4-ol (0.13 g, 0.54 mmol), and triphenylphosphine (0.17 g, 0.64 mmol). The mixture was stirred at room temperature overnight and then concentrated under reduced pressure. The residue obtained was purified by flash chromatography (silica gel, ethyl acetate/hexanes=3/7) to afford tert-butyl 4-(6-(1-(4-(trifluoromethyl)phenyl)piperidin-4-yloxy)benzo[d]thiazole-2-carboxamido)piperidine-1-carboxylate (compound 14) as a white solid (0.28 g, 86%). 1H-NMR (CDCl3, 300 MHz): δ 7.95 (m, 1H), 7.48 (m, 3H), 7.27 (m, 1H), 7.17 (m, 1H), 6.97 (m, 2H), 4.62 (m, 1H), 4.12 (m, 3H), 3.61 (m, 2H), 3.29 (m, 2H), 2.95 (m, 2H), 2.06 (m, 6H), 1.56 (m, 2H), 1.41 (s, 9H) ppm; MS (ESI): 605.5 (M+1).
