Versuchsvorschrift

3,4,5-Trimethoxybenzaldehyde (992 mg) and methyl azidoacetate (2.91 g) were dissolved in dry methanol (2 mL), and a dry methanol solution (10 mL) of sodium (582 mg) was added dropwise to the solution at 0° C. over 2 hours under an argon atmosphere. After stirring the reaction mixture for 30 minutes as it is, it was concentrated under reduced pressure, and water was added to the residue to collect crystals deposited by filtration. The crystals were washed with water and dried to obtain the title compound.
