Conditions

Temperature
90 °C

Procedure

26.0 g of 2-(2,6-dichlorophenyl)-thiazoline-4,5-dione are suspended in 250 ml of dry toluene and heated to 90° C. while stirring. Gas is evolved and a violet solution is obtained, to which is added 16.2 g of 3,4-dichloroaniline dissolved in 30 ml of toluene. After stirring for 15 minutes the solution is cooled and the precipitate obtained is drawn off. Yield 20.1 g. Melting point 168° C.
