Participants

Reaction Steps

311 mg of hydroxybenzotriazole and 445 μl of diisopropylcarbodiimide were added to a solution of 160 mg of 3-methoxybenzoic acid in 10 ml of dimethylformamide, after which 200 mg of 3-methyl-5-phenyl-1H-pyrazol-4-ylamine were added; the mixture was then stirred at RT for 12 h, after which water was added and the whole was extracted with methylene chloride. The organic phase was dried over magnesium sulfate, concentrated under reduced pressure and purified by means of HPLC (Merk-Hibar-Lichrospher 100-RP-18, water (0.1% trifluoroacetic acid)/acetonitrile (0.1% trifluoroacetic acid)=80/20→10/90). The following was obtained: 4 C17H15N3O2 (293.33); MS (ESI) 294 (M+H).
