reaction of 4-chloro-2-oxo-2H-chromene-3-carbaldehyde with various aromatic amines in the presence of ultrasound. Some of these compounds were converted to the corresponding 2-(3-(hydroxymethyl)quinolin-2-yl)phenols and further structure elaboration of a representative quinoline derivative is presented. Molecular structure of two representative compounds was confirmed by single crystal X-ray diffraction
