53137-27-2. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 53137-27-2, Name is 2,4-Dimethylthiazole-5-carboxylic acid. In a document type is Article, introducing its new discovery.

A novel series of 1,2,4-triazol-3-yl-azabicyclo[3.1.0]hexanes with high affinity and selectivity for the DA D3 receptor and excellent pharmacokinetic profiles was recently reported. We also recently discussed the role of the linker associated with the triazole moiety. In this manuscript, we are reporting a detailed exploration of the region of the receptor interacting with the amine terminus of the scaffold wherein SAR and developability data associated with these novel templates was undertaken.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.53137-27-2,2,4-Dimethylthiazole-5-carboxylic acid,as a common compound, the synthetic route is as follows.

53137-27-2, EXAMPLE 3 (Compound No. 3) To a solution of imidazole (2.27 g; 40 mmol) in dry tetrahydrofuran (60 ml) was added dropwise thionyl chloride (1.20 g; 10 mmol) under ice-cooling while stirring. After the resultant mixture was turned to room temperature, 2,4-dimethyl-5-thiazolecarboxylic acid (1.57 g; 10 mmol) was added thereto at once, and stirring was continued for 30 minutes. To the mixture was added dropwise a solution of 2-(2-thienyl)aminoacetonitrile (1.65 g; 12 mmol) in dry tetrahydrofuran under ice-cooling, and the resultant mixture was stirred at room temperature for 1 hour. After completion of the reaction, tetrahydrofuran was removed under reduced pressure to separate the residue. Water was added to the residue, which was extracted with ethyl acetate. The ethyl acetate layer was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give crude oil. The oil was purified by silica-gel column chromatography (eluent:n-hexane:ethyl acetate=2:1 volume) to give crude crystals. Recrystallization from n-hexane/ethyl acetate gave 1.80 g of 2-(2,4-dimethylthiazole-5-carboxamido)-2-(2-thienyl)acetonitrile as colorless crystals. m.p., 127.5-128.5 C. Yield, 65%.

As the paragraph descriping shows that 53137-27-2 is playing an increasingly important role.
