Reaction Steps

2.5 g of 3-methyl-2-methylthionaphtho[2,1-d]thiazolium p-toluenesulfonate (synthesized from 2-methylthionaphtho[2,1-d]thiazole and methyl p-toluenesulfonate), 1.7 g of 3-methoxyethoxyethoxyethylthiazolidine-4-on-2-thion and 30 ml of acetonitrile were fed into a 100 ml three-necked flask, and cooled to 5° C. 1.2 g of triethylamine was added to the resultant mixture. After stirring at 10° C. for 4 hours, yellow precipitates thus formed were suction-filtered, washed with 10 ml of acetonitrile twice and dried to obtain the intended compound.
