Reaction Steps
Pieces of sodium (3.678 g, 160 mmol) were added to ethanol (200 ml) over a period of 30 minutes. The resulting solution was cooled to −18° C. and a mixture of 2,3-dimethoxybenzaldehyde (4.832 g, 40 mmol) and ethyl azidoacetate (20.64 g, 160 mmol) was then added, over one hour, at a rate which allowed the temperature to be maintained below −15° C. After three hours, the solution was stored at 5° C. for two days in order to give a crystalline product which was collected. and washed with cold hexane in order to give a pure product in the form of a yellow oil.
