Procedure
Following a procedure similar to that described in Example 1A but employing 4.5 g of 2-(1-ethyl-2-methyl-3-indolylcarbonyl)benzoic acid and 3.4 g of 4-acetamido-N-phenylaniline there was obtained 3.8 g of 3-(1-ethyl-2-methyl-3-indolyl)-3-[N-(4-acetamidophenyl)-N-phenylamino]phthalide, m.p. 93°-116° C. A toluene solution of the product contacted with acidic clay or phenolic resin developed a yellow-colored image.
