Abstract
A procedure for the preparation of nitro-phthalides of the formula **(See formula)** in which E is a radical of the formula **(See formula)** X and X'each represent alkyl with 1 to 12 carbon atoms, alkoxy with 1 to 12 carbon or acyloxy atoms with 2 to 12 carbon atoms, and X can also be hydrogen, Z represents hydrogen, alkyl with 1 to 12 carbon or phenyl atoms, Y represents hydrogen, alkyl with 1 to 12 carbon atoms, benzyl or cyanoethyl, R1, R2, R'1 and R'2 represent, independently of each other, hydrogen, C1-C12-alkyl, C2-C8-alkoxyalkyl, C5-C6-cycloalkyl, benzyl or phenyl and benzene ring B may be further substituted by halogen, nitro or an amino group optionally substituted by alkyl with 1 to 6 carbon atoms, characterized by reacting one mole of a nitro-phthalic anhydride of the formula **(See formula)** or a respective isomeric mixture, with one mole of an indole of the formula **(See formula)** in which Y, Z and B have the meaning set forth above, and one mole of an aminobenzene of the formula **(See formula)** in which R1, R2 and X have the meaning set forth above, and, where appropriate, because one mole of said nitro-phthalic anhydride is reacted with one mole of each of the aforementioned aminobenzenes and an aminobenzene of the formula **(See formula)** in which R'1, R'2 and X'have the meaning stated above.
