To a mixture of 2-methoxy-2-(quinolin-5-yl)acetohydrazide (0.149 g, 0.65 mmol) and 3,4,5-trimethoxybenzaldehyde (0.138 g, 0.70 mmol) in absolute ethanol (5 mL) was added acetic acid (1 drop). The mixture was heated at 60° C. for 17 hours. After cooling to room temperature, the solid was collected on a Büchner funnel and rinsed with ethanol and diethyl ether then dried in vacuo to give (E)-2-methoxy-2-(quinolin-5-yl)-N′-(3,4,5-trimethoxybenzylidene)acetohydrazide (6-1) as a white powder (0.197 g, 75% yield).
