실험 절차

DIPEA (290 mg, 2.26 mmol) was added to a stirred solution of 5-pyridin-3-yl-1H-pyrazole-3-carboxylic acid hydrochloride (prepared by the method used for the synthesis of Intermediate 29, starting from 3-acetylpyridine) (100 mg, 0.44 mmol) in DMF (2 mL) followed by HOBt (63 mg, 0.46 mmol) and EDCI.HCl (90 mg, 0.46 mmol). After 5 minutes 2-amino-1-[4-(3-trifluoromethyl-phenoxy)-piperidin-1-yl]-ethanone hydrochloride (150 mg, 0.44 mmol) (prepared according to Step 1 and 5 of the General Scheme) was added to the reaction mixture and stirring was continued at ambient temperature overnight. The reaction mixture was diluted with cold water, extracted with ethyl acetate, dried over sodium sulfate and concentrated under reduced pressure The residue was purified by filtering through 60-120 silica gel column and filtrate collected was concentrated under reduced pressure to afford 138 mg (66% Yield) of 5-pyridin-3-yl-1H-pyrazole-3-carboxylic acid {2-oxo-2-[4-(3-trifluoromethyl-phenoxy)-piperidin-1-yl]-ethyl}-amide. LC/MS [M+H]+: 474, 94.7%. 1H NMR (300 MHz, DMSO-d6): δ 13.8 (s, 1H), 9.4 (s, 1H), 8.56 (d, 1H), 8.16 (m, 1H), 7.46 (m, 2H), 7.22 (m, 4H), 4.8 (m, 1H), 4.2 (d, 2H), 3.9 (m, 1H), 3.7 (m, 1H), 3.44 (m, 2H), 1.9 (m, 2H), 1.6 (m, 2H).
