Condensation of 4‐chloro‐2‐oxo‐2 H ‐chromene‐3‐carbonitrile ( 1 ) with heteroarylamines 2a‐d in acetonitrile containing a catalytic amount of triethylamine followed by spontaneous intramolecular cyclization gave the novel coumarin derivatives 3a‐d , respectively. These compounds underwent acid hydrolysis giving the corresponding oxoderivatives 4a‐d . The structural assignments of the synthesized compounds were based on elemental, IR, 1 H and 13 C NMR analyses.
