Yield:609-72-3 99%

Reaction Conditions:

with 0.72KNaX-BS zeolite at 150; for 1 h;Reagent/catalyst;

Steps:

Methylation of anilines with dimethyl carbonate. General procedure.
General procedure: Into a pressure microreactor of stainless steel of 17 mL capacity or into a glass ampule (20 mL) (results of the parallel runs were virtually identic) was charged 5-10 wt % of catalyst (0.94HY-BS, NaY-BS, 0.72KNaX-BS), 100 mmol of aniline or its derivative, and 400 mmol of dimethyl carbonate. The reactor was hermetically closed (the ampule was sealed), and was heated for 1-4 h at 150 °C. After the end of the run the reactor was cooled to room temperature, opened, the reaction mixture was filtered through a bed of Al2O3. Dimethyl carbonate was distilled off, the residue was distilled at atmospheric pressure or in a vacuum, or crystallized from ethanol.
