Reference of 886365-46-4, Adding some certain compound to certain chemical reactions, such as: 886365-46-4, name is 5-Chloro-3-methylpyridine-2-carboxylic acid,molecular formula is C7H6ClNO2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 886365-46-4.
To a solution of tert-butyl ((3aR,4R,8S)-4-(6-amino-3-fluoropyridin-2-yl)-4,7,7- trimethyl-8-oxido-3,3a,4,7-tetrahydro-2H-isothiazolo[l,5-a][l,4]thiazin-6-yl)carbamate (Int- 39BA, 150 mg, 0.35 mmol) in THF (20 mL) was added 5-chloro-3-methylpicolinic acid (92.4 mg, 0.53 mmol) followed by T3P (1.1 g, 1.75 mmol, 50% in ethyl acetate), and diisopropylethylamine (267 mg, 2.1 mmol). The reaction was stirred at 70 C for 4 h. After that, the reaction mixture was diluted with aqueous saturated sodium hydrogencarbonate solution (20 mL) and extracted with ethyl acetate (3 x 30 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated to give a crude product. The crude was purified by preparative TLC (silica gel, dichloromethane / ethyl acetate 1: 1, UV) to yield, after drying in vacuo, the title compound as a yellow solid (100 mg, 50% yield). MS (ES+) m/z 579.2 [M+H].
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 886365-46-4, 5-Chloro-3-methylpyridine-2-carboxylic acid, other downstream synthetic routes, hurry up and to see.
