Reaction Steps
70 mg (1,4-bis-(4-fluoro-phenyl)-1H-imidazol-2-yl)-acetic acid ethyl ester, 58 mg 1-(4-methoxy-pyridin-2-yl)-piperazine and 0.05 mLN,N-diisopropylethylamine in 2 mL NMP was stirred 50 min. at 180° C. under microwave condition. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried and evaporated. The residue was purified by HPLC (column: Waters Symmetry 50×140 mm 7 μm, mobile layer: water+0.3% HCOOH/methanol 10% until 90% in 14 min) to give 31 mg desired product.
