실험 절차

A 300 mg portion of 2-(1,3-dihydro-2H-benzimidazol-2-ylidene)-1-[3-(1,2-dihydroxyethyl)phenyl]-3-(3-fluorophenyl)propane-1,3-dione and 200 mg of 1,1′-carbonyldiimidazole were dissolved in 7 ml of Tol and stirred at 80° C. for 12 hours. After concentration of the reaction liquid, the thus formed residue was purified by a silica gel column chromatography to obtain 30 mg (9%) of 2-(1,3-dihydro-2H-benzimidazol-2-ylidene)-1-(3-fluorophenyl)-3-[3-(2-oxo-1,3-dioxolan-4-yl)phenyl]propane-1,3-dione as a yellow solid from a chloroform-methanol (10:1) eluate. ES+: 445
