摘要:
Reactions of 2,6-diisopropylaniline and its 4-bromo and 4-thiocyanato derivatives with methyl iodide in dimethylformamide in the presence of potassium carbonate gave exclusively the corresponding N,N-dimethyl-substituted products. Heating of 2,6-diisopropylaniline and 2,6-diisopropyl-4-thiocyanatoaniline with methyl iodide without a solvent afforded only N-methyl derivatives.
