To a solution of 3,8-dihydroxy-2,9-dimethyl deca-3,7-diene-5,6-dione 2 [1] (452 g, 2 mmol) in absolute ethanol (15 mL) was added the 4-methylorthophenylenediamine 1 (244 mg, 2 mmol) and the mixture was refluxed for 90 min [2] . The orange precipitate 3 was filtred off, washed with ethanol and dried in air.
Yield: (400 mg , 64 %).
Melting point: 98 - 99 °C (EtOH).
IR (KBr, cm-1): 2960 (CH of CH3) ; 1560 (C=O).
1H-NMR (200 MHz, CDCl3) d ppm: 14.66 (s, 2H, N-H); 14.46 (s, 2 H, N-H); 6.89 (m, 3H, CH Benz); 5.71 (s, 1H, =CH); 5.69 (s, 1H, =CH); 2.68 (m, 2H, C-H, J = 6.9 Hz); 2.32 (s, 3H, CH3 ); 1.9 (d, 12H, CH3, J = 6.9 Hz).
