Conditions

Temperature
120 °C

Procedure

9.30 g of 6-chloro-1H,3H-benzo[de]isochromene-1,3-dione and 4.46 g of hydrochlorided cystamine hydrochloride are suspended in 50 ml of N-methylpyrrolidone (NMP). 5.5 g of diisopropylethylamine are added and the mixture is heated with stirring at 120° C. After two hours, 50 ml of NMP are added and the mixture is kept with stirring at 120° C. for 3 hours. After cooling, the precipitated product is recovered and the filtered solution is extended by addition of 200 ml of water, and a second precipitate is recovered. The precipitates are washed with water and dried. 11.46 g of white powder are recovered. The analyses show that the product is in accordance with the expected product.
