    The invention discloses a method for preparing N-methyl formanilide. The prior method adopts N-methylaniline to react with formic acid to prepare the N-methyl formanilide, is balanced reaction of esterification and hydrolysis, and requires continuous removal of water generated during the reaction so as to require superfluous anhydrous formic For example, the dye called aniline yellow is produced by mixing aniline and cold solution of diazonium salt and then shaking it vigorously. Aniline yellow is obtained as a yellow solid. Similarly, a cold basic solution of Naphthalen-2-ol (О’-naphthol) give the intensely orange-red precipitate.
