5-Isoquinolinethiol 500 mg (3.1 mmol) was dissolved in DMF 20 ml, 6-chloro-1-ethyl-2-methyl-5-nitro-1H-benzo[d]imidazole 910 mg (3.1 mmol) and potassium carbonate 1.29 g (9.3 mmol) were added, and the mixture was stirred for 6 hours at 130° C. The reaction mixture was concentrated under reduced pressure, the residue was crystallized with ethyl acetate, and 1-ethyl-6-(5-isoquinolylsulfanyl)-2-methyl-5-nitro-1H-benzo[d]imidazole 410 mg (35.8%) was obtained.
