Procedure

Following a procedure similar to that described in Example 1 but employing 2.6 g of 2-[4-(dimethylamino)benzoyl]benzoic acid and 2.1 g of 4-(dimethylamino)-N-phenylaniline there was obtained 2.2 g of 3-[4-(dimethylamino)phenyl]-3-{[4-(dimethylamino)phenyl]phenylamino}phthalide, m.p. 163°-166° C. A toluene solution of the product contacted with acidic clay or phenolic resin developed a brown-colored image.
