Abstract

In the present study, trans-3-(2,4-dichlorophenyl)-1-(4-(dimethylamino)phenyl)prop-2-en-1-one (trans
2,4-dimethyl amino chalcone) was synthesized by Claisen-Schmidt reaction in the presence of aqueous
alcoholic alkali solution by condensation of a substituted acetophenone with substituted benzaldehydes,
Then, The photosynthesis of 4-(5,7-dichloro-8aH-chromen-2-yl)-N,N-dimethylaniline (2,4-dimethylamino
chromene) was accomplished from the irradiation of the( trans 2,4-dimethyl amino chalcone) with xenon
light. The products were characterized by UV-Visible, FT-IR, 1HNMR, thin layer chromatography
Elemental analysis(CHNO) and liquid chromatography-quadrupole-time-of-flight mass spectrometry
(LC-Q-ToF-MS).
