A general and convenient synthesis of 6-methoxyquinoline-3-carboxamides commencing with a cyclization step that involves ρ-anisidine and diethyl (ethoxymethylene)malonate is described. An additional tetrahydroquinoline scaffold 19 is prepared from 6-methoxyquinoline-3-carboxamide and this represents a novel serotinergic lead structure. These compounds show reasonable affinity at 1 × 10–6 M, and docking
