실험 절차

A solution of (3,4-diaminophenyl)-3-hydroxy-2-(phenylmethyl)-2,3-dihydro-1H-isoindol-1-one) (0.42 g, 1.21 mmol) and 3-chloropropyl [imino(methylthio)methyl]carbamate (0.27 g, 1.31 mmol) in glacial acetic acid (5.0 mL) was heated to 80° C. for 20 minutes. The reaction mixture was poured into ice water and the pH was adjusted to 9 by the addition of 2M aqueous sodium hydroxide. The precipitated product was extracted with ethyl acetate (100 mL) and the organic layer was washed with brine and dried over anhydrous sodium sulfate, followed by the evaporation of the solvent. The resulting crude product was purified by silica gel flash chromatography (chloroform-acetonitrile 95:5 to 9:1 eluent) to give 3-chloropropyl {6-[1-hydroxy-3-oxo-2-(phenylmethyl)-2,3-dihydro-1H-isoindol-1-yl]-1H-benzimidazol-2-yl}acetate (0.64 g, 71% yield). MS (EI) for C26H23ClN4O4: 491 (MH+).
