278 mg (3,5-diphenyl-pyrazol-1-yl)-acetic acid was dissolved in 5 mL DMF. 321 mg TBTU and 172 μL DIPEA were added to this solution and the mixture was stirred for a few minutes at RT. 164 mg 2-(1-piperazinyl)-pyrimidine was added and stiffing was continued for 30 min. Then 10 mL of a 1M NaOH solution and 50 mL CH2Cl2 were added, the organic phase was separated. The solvent was removed and the residue was purified by flash chromatography (silica gel, DCM/MeOH/NH3 0-5%). Diethylether was given to the residue and the precipitate was filtered to yield 310 mg of the desired compound.
