The product 3 was prepared by the condensation of dienone 2 [1] (1g, 3.1 mmol) with 3,4-diaminotoluene 1 (0.38 g, 3.1 mmol) by refluxing an ethanol (50 mL) solution for 1 h. under nitrogen [2,3]. The solid that formed, was purified by chromatography on silica gel (CH2Cl2). The colour of the compound: red-brown; yield : (0.9 g, 71%).
Melting point = 180-182°C ( CH2Cl2).
IR (KBr, cm-1) : 2950 (CH3) ; 1600 (C=O) ; 1480 (C=C).
1H-NMR (200 MHz, CDCl3) d : 7.89 (d, 4H, J=8.04 Hz, CH Benz) ; 7.3 (d, 4H, J=8.04 Hz, CH Benz) ; 7.05 (m, 3H, -CH Benz) ; 6.49 (s, 1H, -CHCO) ; 6.47 (s, 1H, -CHCO) ;
2.43 (s, 6H, 2CH3) ; 2.37 (s, 3H, CH3).
