With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.85064-61-5,Tetrahydropyranyl-4-acetic acid,as a common compound, the synthetic route is as follows.
A solution of methyl 2-amino-5-iodobenzoate (7.02 g, 25.3 mmol) and 2-(tetrahydro-2H-pyran-4-yl)acetic acid (3.76 g, 26.1 mmol) in pyridine (25 mL) was stirred at ?-40¡ã C. under argon while POCl3 (2.58 g, 27.8 mmol) was added dropwise over 3 minutes. The cold bath was immediately removed and the reaction was allowed to stir for 1 hour. The reaction was then diluted with water (75 mL) and extracted with DCM (75 mL). The combined orange organic layers were washed with 6 M aqueous HCl (50 mL), 1 M aqueous HCl (50 mL), and 2 M aqueous K3PO4 (50 mL), dried (Na2SO4), filtered, and concentrated to provide the title compound as an orange solid., 85064-61-5
As the paragraph descriping shows that 85064-61-5 is playing an increasingly important role.
