Method for synthesizing 6-methyl-dibenzothienophridine

Abstract

The invention relates to a method for synthesizing 6-methyl-dibenzothienophridine, comprising the following steps of: in mixed solvent of ethanol and water, taking 2,2-dithiosalicylic acid as shown in the formula (II) and pyridine derivative as shown in the formula (III) as raw materials; reacting for 24-60 hours at 80-200 DEG C and in 2-3 atmospheric pressures in the presence of sodium azide; and processing the reaction liquid after the reaction is finished to obtain the 6-methyl-dibenzothienophridine as shown in the formula (I), wherein the molar ratio of the 2,2-dithiosalicylic acid to the pyridine derivative is 1-10:1; the molar ration of pyridine derivative to the sodium azide is 1:1-5; and the volume ratio of ethanol to water in the mixed solvent is 1-5:2. The method has simple operation and little environmental pollution and reduces the production cost. The product synthesized by the method can be used for preparing nano devices.
