실험 절차

60 μl (0.7 mMol) oxalylchloride are added to a solution of 200 mg (0.45 mMol) 6-[1-(3-trifluoromethyl-phenylcarbamoyl)-2,3-dihydro-1H-indol-5-yloxy]-pyrimidine-4-carboxylic acid in 4 ml CH2Cl2 and 1 drop of DMF. After 1 h at rt, the solution is concentrated in vacuo. The residue is re-dissolved in THF and 108 μl (0.97 mMol) 1-methylpiperazine are added dropwise. After 2 h stirring, the mixture is diluted with EtOAc and sat. Na2CO3, the aqueous layer separeted off and extracted twice with EtOAc. The organic phases are washed with water and brine, dried (Na2SO4) and concentrated. Chromatography (Combi Flash; EtOAc→EtOAc/EtOH+2% Et3N 4:1) and crystallization from EtOAc gives the title compound: m.p.: 203-204° C.; TLC(EtOAc/EtOH/NH3conc. 90:10:1): Rf=0.21.
