Procedure

When an equivalent amount of 3-ethyl-2-benzimidazolinone is substituted for 1-ethoxycarbonyl-2H-indazolin-3-one and 2-bromochloroethane is substituted for 1,2-dibromoethane in the procedure of Example 19 using tetrahydrofuran as solvent, 2-(3-ethyl-2,3-dihydro-2-oxo-1H-benzimidazol1-yl)ethyl chloride is isolated after column chromatography (3-ethyl-2-benzimidazolinone, Aldrich, 6%, A).
