1-Hydroxybenzotriazole → HCID 178425687, 화합물

DIPEA (155 mg, 1.2 mmol) was added to a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (100 mg, 0.4 mmol) in DMF (2 mL) followed by HOBt (54 mg, 0.4 mmol) and EDCI.HCl (84 mg, 0.44 mmol). After 2 minutes 4-m-tolyloxy-piperidine hydrochloride (107 mg, 0.4 mmol) (prepared by method used for the synthesis of Intermediate 15) was added to the reaction mixture and stirring was continued at ambient temperature overnight. The reaction mixture was diluted with cold water, the solid collected. The solid was purified by washing with 10% MeOH in CHCl3 to afford 92 mg (56% Yield) 5-phenyl-1H-pyrazole-3-carboxylic acid [2-oxo-2-(4-m-tolyloxy-piperidin-1-yl)-ethyl]-amide. LC/MS [M+H]+: 419, 95.4%. 1H NMR (300 MHz, DMSO-d6): δ13.8 (m, 1H), 8.6 (m, 1H), 8.0 (m, 2H), 7.8 (m, 2H), 7.4 (m, 4H), 7.2 (m, 2H), 6.8 (m, 3H), 4.6 (m, 1H), 4.2 (m, 2H), 3.8 (m, 1H), 3.6 (m, 1H), 3.4 (m, 1H), 3.3 (m, 1H), 2.3 (s, 3H), 2.0 (m, 2H), 1.6 (m, 2H).
