To a mixture of 4-methoxyphenyl hydrazine (0.359 g, 2.06 mmol) in toluene (30 mL) is added 1,3 cyclohexanedione (0.231 g, 2.06 mmol). The mixture is refluxed for 30 minutes. The toluene is removed under reduced pressure and the residue triturated in CH2Cl2: CH3OH (95:5). A white solid is filtered to give 0.2903 g (65%) of the title compound; IR (drift) 3160, 3141, 3114, 3064, 1619, 1588, 1474, 1434, 1277, 1215, 1140, 1015, 844, 802, 791 cm−1.
