Method for synthesizing quaternary ammonium salt -73

The invention relates to the technical field of chemical synthesis, and provides a synthesis method of quaternary ammonium salt -73, which comprises the following steps: (1) thionamide generation thioreaction, and obtaining a compound of formula (I). (2): The compound of formula (I) reacts with chloroacetone to yield the compound of formula (II). (3) The compound of formula (II) is desalted, and the compound of formula (III) is obtained after dehydrogenation and iodoheptane in the presence of an organic solvent. (4) Of formula (III) and iodoheptane are reacted to give the compound of formula (IV), i.e. the quaternary ammonium salt -73. The preparation method has the advantages of cheap and easily available raw materials, simple operation, controllable reaction process, easy separation and purification of the product, high total yield, high purity and suitability for industrial scale production.
