Abstract

Indolines of the formula <IMAGE> in which R1 represents hydrogen or C1-C4-alkyl and R2 and R3 independently of one another in each case represent hydrogen, C1-C4-alkyl or phenyl, are prepared by cyclodehydratation of a 2-(2'-aminophenyl)ethanol of the formula <IMAGE> in which R1, R2 and R3 are as defined above, at 150-350 DEG C, in the presence of an amorphous alumosilicate. The indolines of the above formula are valuable intermediates for the preparation of crop protection agents.
