Procedure

Threat the diethylacetal of 2-hydroxy-4-aminobutanal with acetic anhydride in pyridine followed by treatment of the resulting diethylacetal of 2-acetoxy-4-acetamidobutanal with sodium hydride and methyl iodide to obtain the diethylacetal of 2-acetoxy-4-(N-methylacetamido)butanal. Remove the acetal protecting group by means of acid to obtain 2-acetoxy-4-(N-methylacetamido)butanal.
