Reaction Steps

To a suspension of 4-amino-1-(3-(5-(N-methyl-N-phenylsulfamoyl)-2-(methylamino)phenylamino)-3-oxopropyl)pyridinium chloride (0.2 g, 0.00042 mol) in acetonitrile (8 ml), thionyl chloride (0.2 ml) was added. After boiling the reaction mixture for 10 min, it was left to stand at room temperature for 24 h and then diluted with diethyl ether (8 ml). The precipitate formed was collected by filtration and crystallized from a 10:1 mixture of acetonitrile with dehydrated ethanol. The yield of 4-amino-1-(2-(1-methyl-5-(N-methyl-N-phenylsulfamoyl)-1H-benzo[d]imidazol-2-yl)ethyl)pyridinium chloride was 0.055 g (26%).
