実験手順
DIPEA (137 mg, 11.0 mmol) was added to stirred solution of 1-phenyl-1H-[1,2,3]triazole-4-carboxylic acid (50 mg, 0.26 mmol) in DMF (3 mL) followed by HOBT (39 mg, 0.29 mmol) and EDCI (100 mg, 0.53 mmol). After 2 minutes of stirring, 2-amino-1-[4-(3-trifluoromethyl-phenoxy)-piperidin-1-yl]-ethanone hydrochloride (prepared according to Step 1 and 5 of the General Scheme) (90 mg, 0.26 mmol) was added and the resulting mixture was stirred at room temperature overnight. The reaction mixture was diluted with cold water and extracted with ethyl acetate. The organic layer collected was dried over sodium sulfate and concentrated under reduced pressure afforded residue. The residue was purified by column chromatography (using 60-120 silica gel and 50% EtOAc in hexane as eluent) afforded 63 mg (50% Yield) of 1-phenyl-1H-[1,2,3]triazole-4-carboxylic acid {2-[4-(2-chloro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LC/MS [M+H]+: 474.14, 94.1%. 1H NMR (300 MHz, DMSO-d6): δ 9.38 (s, 1H), 8.5 (t, 1H), 8.0 (d, 2H), 7.7-7.6 (t, 2H), 7.6-7.5 (t, 2H), 7.36-7.24 (t, 3H), 4.8 (q, 1H), 4.25 (d, 2H), 4.0-3.8 (m, 1H), 3.8-3.7 (m, 1H), 3.5 (m, 2H), 2.0 (m, 2H), 1.8-1.5 (m, 2H).
