실험 절차
59.0 mg (0.28 mmol) (4-Amino-3-fluoro-phenyl)-pyrrolidin-1-yl-methanone was dissolved in 6 mL THF and 3 mL water. 238.0 mg (2.83 mmol) NaHCO3 were added. Finally 75.6 mg (0.26 mmol) 2-Trichloromethyl-1H-benzoimidazole-4-carboxylic acid methyl ester were added and the resulting mixture was stirred vigorously for 3 h at RT. The mixture was diluted with 25 mL CH2Cl2 and washed with a saturated NaHCO3-solution and with brine. The organic layer was dried over anhydrous MgSO4 and concentrated under reduced pressure. After purification by preparative RP-HPLC (CH3CN/H2O gradient and 0.05% formic acid) pure 2-[2-Fluoro-4-(pyrrolidine-1-carbonyl)-phenylcarbamoyl]-1H-benzoimidazole-4-carboxylic acid methyl ester was obtained in form of a colorless amorphous solid.
