Versuchsvorschrift
A 6.27 gm. portion of 1-(2-acetoxyethyl)-2-hydroxymethyl-5-nitroimidazole is refluxed with 13.3 gm. of lead tetraacetate in 200 ml. of benzene for 18 hours, cooled, and filtered. The filtrate is washed with 50 ml. of saturated sodium carbonate solution, and the organic phase is separated therefrom. The remaining aqueous phase is twice extracted with 30 ml. of chloroform, and then combined with the above separated organic phase. The combined organic phases are dried under magnesium sulfate, and filtered. The organic solvents are then removed in vacuo, giving the above aldehyde.
