実験手順

To a stirred solution of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-[4-(2-nitro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide (0.07 g, 0.00016 mole) in a mixture of methanol (5 mL) and THF (5 mL) was added 10% Pd/C (0.01 g). The resulting mixture was stirred under an atmosphere of hydrogen for 30 minutes. The mixture was then filtered through celite, and the celite was washed with methanol. The combined organic layers were concentrated under reduced pressure. The resulting residue was re-crystallized from a hexane/chloroform mixture to afford 0.025 g (39%) of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-[4-(2-amino-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 420.2 (M+1)+, 96.9%, 1H NMR (DMSO-d6): δ 8.1 (bs, 1H), 7.8 (d, 2H), 7.5-7.3 (m, 3H), 7.1 (m, 1H), 6.85 (d, 1H), 6.7 (m, 2H), 6.5 (m, 1H), 4.7 (s, 2H), 4.6 (s, 1H), 4.2 (s, 2H), 3.9 (m, 2H), 2.0 (m, 2H), 1.8 (m, 2H), 1.4 (m, 2H).
