Versuchsvorschrift

To a 4-mL vial was added 4-Isopropyl-5-(5-(2-methoxyethyl)-4H-1,2,4-triazol-3-yl)-2-methylbenzoic acid (compound 198.6, 31 mg, 0.10 mmol, 1.0 equiv), 4-(piperidin-4-yl)benzonitrile hydrochloride (compound 1.5, 23 mg, 0.10 mmol, 1.0 equiv), 1-hydroxybenzotriazole hydrate (20 wt % water) (22 mg, 0.13 mmol, 1.25 equiv), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (21.5 mg, 0.11 mmol, 1.1 equiv), DMF (1 mL) and DIEA (71 μL, 0.41 mmol, 4 equiv). The mixture was stirred at room temperature for 24 hours then diluted with ethyl acetate (10 mL) and washed with brine (10 mL). The aqueous was back extracted with ethyl acetate (3 mL) and the combined organics was washed with saturated NaHCO3 (5 mL), 1 M NaH2PO4 (5 mL), and brine (5 mL). The organics were dried (Na2SO4), filtered and removed in vacuo. The crude residue was purified by preparative TLC (DCM/8% MeOH) to obtain the title compound as an off white solid (23 mg, 48%). m/z (ES+) 472 (M+H)+.
