Procedure

A mixture of 11.15 g of 5H-dibenz[b,e]azepin-6,11-dione and 600 ml of glacial acetic acid is heated on a steam bath until the solid dissolves. To the solution (70° C.) is added chlorine gas. chlorine is bubbled through the solution until a precipitate begins to form. The mixture is allowed to cool to room temperature and is filtered to give 7.3 g of product, m.p. 290° C. to 295° C.
