Selective Methylation of NH-Containing Heterocycles and Sulfonamides Using N,N-Dimethylformamide Dimethylacetal Based on Calculated pKa Measurements
摘要:
The use of N,N-dimethylformamide dimethylacetal (DMF-DMA) as a suitable methylating agent for the methylation of NH-containing groups and heterocycles has been investigated. Use of ReactArray and calculated pK(a) measurements have allowed additional helpful information to be collated to determine optimum reaction conditions for a variety of substrates.
