Task: Please generate a molecule SMILES based on the text description.
Description: The molecule is an optically active twelve-membered tetraazamacrocycle having a carboxymethyl group attached to each of the nitrogens and a 4-(2-bromoacetamido)benzyl group at the 2-position. It is an azamacrocycle and a tetracarboxylic acid. It derives from a DOTA.
Result: O=C(O)CN1CCN(CC(=O)O)CCN(CC(=O)O)[C@@H](Cc2ccc(NC(=O)CBr)cc2)CN(CC(=O)O)CC1
