Reference of 1370347-50-4, Adding some certain compound to certain chemical reactions, such as: 1370347-50-4, name is (S)-1-(3,5-Dichloropyridin-4-yl)ethanol,molecular formula is C7H7Cl2NO, 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 1370347-50-4.

(S) -1- (3,5-dichloropyridin-4-yl) ethanol (VI)(1.8 g, 9.37 mmol) and triethylamine (3.42 g, 50.61 mmol) were dissolved in anhydrous dichloromethane (50 ml) and methanesulfonyl chloride (1.29 g, 11.25 mmol) was added dropwise with stirring under ice bath. The reaction solution was poured into saturated sodium bicarbonate solution, the organic layer was separated, and the organic layer was washed with methylene chloride, and the organic layer was combined and the organic layer was washed with saturated brine. The organic layer was washed three times with the organic layer and the organic layer After drying over anhydrous sodium sulfate, the dichloromethane was distilled off under reduced pressure and purified by silica gel column chromatography (petroleum ether: ethyl acetate = 20: 1) to give 2.15 g of pure white crystals in a yield of 93%

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. 1370347-50-4, (S)-1-(3,5-Dichloropyridin-4-yl)ethanol, other downstream synthetic routes, hurry up and to see.

Reference of 1370347-50-4, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 1370347-50-4 as follows.

Methanesulfonyl chloride (32.21g, 281.2 mmol) was slowly added to a mixed solution of Example 25F (18g,94mmol) and triethylamine (28.45g, 281mmol) in dichloromethane (400mL) at 0C under an ice bath. The reactionsolution was stirred at room temperature for 4 hours. Upon the completion of the reaction, the reaction was quenchedwith water and extracted with dichloromethane (500mL 3 3). The combined organic phase was dried over anhydroussodium sulfate and evaporated to dryness. The residue was purified by column chromatography to give Example 24G(24g, 88.9mmol, yield 94.8%).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1370347-50-4, its application will become more common.
