Reaction Steps

27.3 g (0.2 mol) of zinc chloride was dissolved in 500 ml of ethylene glycol. To the solution was gradually added 60.4 g (0.4 mol) of 5-methyl-anthranilic acid. After the addition, the mixture was stirred for 2 hours at 130° C. and then dispersed in 3 liters of water. The dispersion was subjected to filtration and the precipitate was washed with water until the filtrate water reached neutrality. The precipitate was then dried at 90° C. to obtain about 40 g of white powder.
