Versuchsvorschrift
DIPEA (316 mg, 2.5 mmol) was added to a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (181 mg, 0.7 mmol) in DMF (3 mL) followed by HOBt (108 mg, 0.8 mmol) and EDCI.HCl (160 mg, 0.8 mmol). After 2 minutes of stirring, 3-(piperidin-4-yloxy)-benzonitrile hydrochloride (50 mg, 0.7 mmol) (prepared according to Step 1 and 5 of the General Scheme) was added and stirring was continued at ambient temperature overnight. The reaction mixture was diluted with water, extracted with ethyl acetate, washed with brine and concentrated The residue was purified by column chromatography (using neutral alumina and 5% MeOH in CHCl3) afford 44 mg (14.3% Yield) of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-[4-(3-cyano-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LC/MS [M+H]+: 473.17, 99.16%, 1H NMR (300 MHz, DMSO-d6): δ 8.1 (m, 1H), 7.8 (m, 2H), 7.6 (m, 4H), 7.4 (m, 3H), 7.1 (b, 1H), 4.8 (m, 1H), 4.2 (m, 2H), 4.0 (m, 1H), 3.8 (m, 1H), 2.0 (m, 2H), 1.5 (m, 2H).
