実験手順

A mixture of 1.5 g (4.1 mmol) of 2-chloromethyl-1-methylbenzimidazol-5-yl-carboxylic acid-N-(n-propyl)-N-(2-ethoxycarbonylethyl)amide and 0.65 g (4.8 mmol) of p-cyanothiophenol was heated in 10 mL of dimethylformamide and 10 mL of diisopropylethylamine for 1 hour to 100° C. The solvent was distilled off in vacuo, the crude product was dissolved in 30 mL ethyl acetate, washed with 30 mL water, and after concentration purified by flash chromatography (silica gel; methylene chloride/ethanol (49:1 to 19:1). Yield: 1.5 g (79% of theory) of brown oil; Rf value: 0.65 (silica gel; ethyl acetate/ethanol/ammonia=90:10:1).
