Abstract
The synthesis of N,N-dimethylacetamide acetal was improved and optimized.Methylation of N,N-dimethylacetamide with dimethyl sulfate at 70℃,followed by alcoholysis with sodium methoxide / methanol mixture at 0 ~5℃ gave the title compound in 72% yield.GC-MS was adopted for structure characterization.The formation of by-products of the reaction was suppressed effectively.
