چکیده
There are three independent mol-eculesi n the asymmetric unit of the title compound, C(18)H(16)BrN(3)O(3), in which the dihedral angles between the indole and benzene rings are 76.9 (2), 4.9 (2), and 70.9 (2)°. All three mol-ecules exist in a trans configuration with respect to the methyl-idene units. In each mol-ecule, there is one intra-molecular O-H⋯N hydrogen bond. In the crystal, N-H⋯O hydrogen bonds occur.
