Abstract

A method for preparing 4-dimethylaminophenol of the formula (I), which comprises adding trimethyl phosphate into p-anisidine of the formula (III), to undergo N-methylation reaction, in which the molar ratio of the p-anisidine of the formula (III) to the added trimethyl phosphate is 1:1 to 1:10; after refluxing, adding an aqueous solution of sodium hydroxide for further refluxing, thereby obtaining a dimethyl-substituted p-anisidine of the formula (II), thermally hydrolyzing the obtained dimethyl-substituted p-anisidine of the formula (II) in the presence of hydrobromic acid, thereby obtaining the desired product.
