C13 deuterated methyl telmisartan and preparation method and application thereof

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.

Aspirin and clopidogrel hydrogen sulfate compound preparation and preparation method thereof

The invention discloses an aspirin and clopidogrel hydrogen sulfate compound preparation and a preparation method thereof, and belongs to the field of pharmaceutical preparations. The aspirin and clopidogrel hydrogen sulfate compound preparation is prepared by mixing and tabletting an aspirin enteric-coated tablet core and clopidogrel hydrogen sulfate quick-release particles. An aspirin enteric-coated tablet is composed of a drug-containing element tablet and two layers of coatings including an enteric coating and an isolation layer coating. Due to the fact that talcum powder and glyceryl monostearate are combined for use, the glyceryl monostearate has a hydrophobic effect, production of salicylic acid can be better slowed down, aspirin stability is better, and an inner isolation layer does not need to be added; and clopidogrel hydrogen sulfate granules are prepared by hot melting granulation. The aspirin and clopidogrel hydrogen sulfate compound preparation can achieve the characteristics that clopidogrel or a medicinal salt thereof can be quickly released in the stomach and the aspirin enteric-coated tablet can be released in the intestinal tract. The preparation method has the advantages of smooth production process, high production capacity, good stability and the like.
