Reaction Steps

14 g of methacrolein were added dropwise, at 100° C., to a solution of 17 g of 4-chloroanthranilic acid and 19 g of sodium m-nitrobenzenesulfonate in 200 g of 57% strength sulfuric acid. The mixture was stirred for 1 hour at 130° C., after which it was diluted with 450 g of water and filtered under suction while hot. The pH was brought to 2-3 with concentrated sodium hydroxide solution, while cooling. The precipitated solid was filtered off under suction, washed with water and dried.
