1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 1-[3-(3-Fluoro-phenylamino)-6,7-dimethoxy-4H-indeno[1,2-c]pyrazol-1-yl]-3-pyrrolidin-1-yl-propane-1,3-dione

Reaction Steps

A mixture of (6,7-Dimethoxy-1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-(3-fluoro-phenyl)-amine (Compound 14) (0.36, 1.0 mmol), 3-Oxo-3-pyrrolidin-1-yl-propionic acid (Compound 28a) (0.157 g, 1.0 mmole), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide (EDC) (0.24 g, 1.25 mmol), hydroxybenzo-triazole hydrate (HOBT) (0.17 g, 1.25 mmol) and DIEA (0.220 mL, 1.25 mmol) was stirred in 10 mL DMF over night at room temperature. The reaction was quenched with saturated NaHCO3 and extracted with EtOAc. The solvent was removed in vacuo and the crude material was prepped on the Gilson. Lyophilization produced a white powder.
