The invention belongs to the field of organic medicinal synthesis, and discloses C13 deuterated methyl telmisartan and a preparation method and application thereof. According to the preparation method, with C13 deuterated methanol as a C13 deuterated raw material, the C13 deuterated telmisartan is synthesized through a four-step reaction. The preparation method comprises the following steps: iodizing the C13 deuterated methanol to obtain C13 deuterated iodomethane; performing a substitution reaction on the C13 deuterated iodomethane and a compound (III) to obtain a compound (IV); performing aSuzuki coupling reaction on the compound (IV) and 2-boro methylbenzoate to obtain a compound (V); performing esterolysis on the compound (V) under an alkaline condition to obtain the C13 deuterated telmisartan. The preparation method is easy and convenient to operate; by the preparation method, a C13 deuterated reagent is saved, the cost is low and purification is easy; a purified product is obtained after rapid preparation and chromatographic purification. A standard deuterated telmisartan substance prepared by the preparation method provided by the invention is high in purity and stable in chemical properties, and can be applied to preparation of an analytical standard substance.
