aromatic hydrocarbons and substituted phenolic derivatives with dimethoxymethane and chlorosulfonic acid was carried out in the presence of 10 mol% of ZnCl2 in a mild and efficient manner undersolvent-freeconditions. In addition, 2,6-dimethyltyrosine was synthesized in high yield via this protocol. GRAPHICAL ABSTRACT
