The 2-formyl-3,5-dimethoxybenzoic acid (2.7 g, 13 mmol) is partially dissolved in 300 mL of ethanol, and 6.2 mL of hydrazine hydrate are then added. The mixture is refluxed for 6 hours. After cooling, the precipitate formed is filtered off and then dried. 2.3 g of a white solid are obtained (86% yield).
