実験手順

To a solution of 5 g of 4-amidino-2,6-dibromophenol in 100 ml of pyridine, while being cooled in ice and stirred, was added 2.4 g of piperonyl chloride. The mixture was stirred for 30 minutes while being cooled in ice, then for 3 hours at room temperature, and mixed with about 300 cc of ethyl ether. The precipitate which was formed was collected by filtration and recrystallized from ethanol to obtain 4.8 g of colorless crystals of 4-amidino-2,6-dibromophenyl 3,4-methylenedioxybenzoate methanesulfonate.
