Abstract
"A METHOD OF PREPARATION OF CHROMOGENIC, FUNDAMENTALLY COLORFUL OR LIGHTLY COLORED FATALIDES", characterized in that the structural formula is: ** (See formula) ** wherein R1 R2, R3 and R4 represent alkyl radicals having no more than 5 carbon atoms, phenyl and hydrogen radicals; R5 represents an alkoxide radical having no more than 5 carbon atoms, or hydrogen. These phthalides are obtained by reacting, in the presence of a metal halide, an indole R3 R4 substituted with phthalic anhydride, in an organic solvent, to obtain the corresponding substituted 3- (2-carboxybenzoyl) indole, reacting this intermediate product with an indole R1 R2 R5 substituted, in the presence of a condensing agent, we will finally obtain the phthalide.
