The product 3 was prepared by the condensation of dienone 2 [1] (1g, 3.11 mmol) with o-phenylenediamine 1 (0.33g, 3.11 mmol) by refluxing an ethanol (50 mL) solution for 1 h. under nitrogen [2,3]. The brown solid that formed, was collected by filtration and was purified by recrystallization in (acetone-chloroform : 50-50). The colour of the compound: red, yield : (1g, 81%).
Melting point : 198-200°C (acetone-chloroform)
IR (KBr, cm-1) : 1570 (C=O) ; 1410 (C=C).
1H-NMR (200 MHz, CDCl3) δ : 7.9 (d, 4H, J= 8.06Hz, -CH Benz) ; 7.31 (d, 4H, J= 8.06Hz, CH Benz) ; 7.15-7.17 (m, 4H, -CH Benz) ; 6.51 (s, 2H, -CHCO) ; 2.44 (s, 6H, 2CH3).
