Versuchsvorschrift

To a stirred solution of 2-(4-chloro-3-dibutylcarbamoyl-5-methyl-pyrazol-1-yl)-5-methoxy-benzoic acid (0.35 g, 0.82 mmol) and (S)-(1,2,3,4-tetrahydroisoquinolin-3-yl)methanol (0.13 g, 0.82 mmol) in dichloromethane (8 mL) under nitrogen atmosphere was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (0.16 g, 0.82 mmol) and hydroxybenzotriazole (0.13 g, 0.82 mmol). The mixture was stirred at ambient temperature for 5 minutes. Triethylamine (0.34 mL, 2.5 mmol) was added to the mixture. The reaction was stirred for 60 hours at ambient temperature. The mixture was washed with water and purified by eluting through a silica gel column with a 10 to 100% ethyl acetate/heptane gradient to afford the title compound (21 mg, 4.5% yield). MS (ESI) [m/e, (M+H)+]=567.3. 1H NMR (400 MHz, chloroform-d) δ ppm 6.75-7.36 (m, 7H), 4.13-5.41 (m, 4H), 3.80-3.96 (m, 3H), 2.51-3.71 (m, 8H), 2.17-2.32 (m, 3H), 1.48-1.68 (m, 4H), 1.19-1.44 (m, 4H), 0.70-0.97 (m, 6H).
