Procedure

Triethylamine (2.8 ml; 0.02 mol) is added to a stirred suspension of 5,6-Dichloro-1,3-diethyl-2-hydroxyiminomethyl benzimidazolium iodide (1.83g, 0.005 mol), 2-(2-chloropropenyl)-3-ethyl benzothiazolium perchlorate andacetic anhydride (0.64 g, 0.006 mol) in acetonitrile (25 ml). The mixture is stirred for 5 minutes, then diluted to 200 ml with ether. The ether is decanted and the residue treated with methanol (25 ml) and chilled. After recrystallization from methanol, the yield of purified dye is 0.37 g (14%)mp indistinct.
