실험 절차

25% KOH (100 mL) was added to 4-[6-(piperidin-1-ylcarbonyl)pyridin-3-yl]morpholine (183 g), and the mixture was refluxed and then neutralized with HCl. The solution was evaporated in vacuum, and the product was extracted with hot isopropanol to give the title compound (yield 71%, 11.5 g). +ESI MS (M+H) 209.7; 1H NMR (400 MHz, DMSO-d6) δ ppm 8.34 (br, s., 1H), 8.03 (d, 1H), 7.65 (dd, 1H), 3.75 (br, s., 4H), 3.40 (br, s., 4H).
