Abstract

"METHOD OF PREPARATION OF CHROMOGENIC, FUNDAMENTALLY COLORLESS OR LIGHTLY COLORED FATALIDES", characterized in that the structural formula is: ** (See formula) ** Where R1 and R2 are alkyl radicals having no more than 5 carbon atoms, aryl and hydrogen radicals. These phthalides are obtained by reacting, in the presence of a metal halide, an R3 R4 aniline substituted, with phthalic anhydride, in an organic solvent, to obtain the corresponding 4'-dialkylaminobenzophenone-2-carboxylic acid substituted. By reacting this intermediate product with an indole R1 R2 substituted, in the presence of a condensing agent, we will obtain the phthalide.
