Versuchsvorschrift
A mixture of 9.8 g (0.05 mol) of methyl 3,4-dimethoxybenzoate and 15 ml of 85% water containing hydrazine was refluxed for 2.5 hours with stirring. The reaction mixture was cooled and the crystals formed were recovered by filtration and washed with water to provide 3,4-dimethoxybenzoic acid hydrazide. The yield was quantitative.
