With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.35272-15-2,2-Methylthiazole-4-carboxylic acid,as a common compound, the synthetic route is as follows.
Example 309 /V-{[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H- pyrazolo[3,4-/j]pyridin-5-yl]methyl}-2-methyl-1,3-thiazoIe-4-carboxamide2-Methyl-1 ,3-thiazole-4-carboxylic acid [e.g. available from Acros Organics] (125mg) was dried overnight under vacuum over phosphorus pentoxide and was then suspended in dry dichloromethane (2ml) and treated at 2O0C with oxalyl chloride (0.077ml) and DMF (1 drop). The mixture was stirred at room temperature for 25mins and was then added dropwise to a solution of Intermediate 16 (240mg) in anhydrous acetonitrile (5ml). DIPEA (0.155ml) was added and the solution stirred at room temperature for 3h. The solution was blown down to dryness and purified by mass directed autoprep HPLC to give a pale orange gum. The gum was further purified using an SPE cartridge (5g, aminopropyl) which had been pre-washed with methanol. Elution with methanol gave Example 309 as a pale orange gum (287mg). LCMS showed MH+ = 429; TRET = 2.37min., 35272-15-2
The synthetic route of 35272-15-2 has been constantly updated, and we look forward to future research findings.
