Process for the preparation of indoline derivatives

Abstract

Novel indoline derivatives of the formula ##STR1## wherein R is H or CH.sub.3 O and the X each are Cl or Br or collectively are --N(CH.sub.2 C.sub.6 H.sub.5)-- or acid addition salts thereof are obtained by treating a 3-hydroxy-1,2,3,4-tetrahydroquinoline of the formula ##STR2## with an inorganic acid halide and, if appropriate, the reacting resulting dihalogen compound with benzylamine or converting a resulting acid addition salt by treatment with a base in the free base or converting a free base by treatment with an acid to an acid addition salt.
