In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6940-76-7, name is 1-Chloro-3-iodopropane belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. name: 1-Chloro-3-iodopropane

335 mg (1.30 mmol) of 4-(3,4-difluorophenyl)phthalazin-1(2H)-one (8n) was dissolved in 10 ml of N,N-dimethylformamide, and 62 mg (1.56 mmol) of sodium hydride were added at 0oC. After being stirred for 30 min, 0.21 ml (1.95 mmol) 3-iodo-1-chloropropane was then added to reaction mixture. After being stirred for 1 h, the reaction mixture was combined with 50 ml of water and extracted with ethylacetate (50 ml X 2) being washed with water and a sodium hydroxide solution, and then the combined organic layer was dried over anhydrous sodium sulfate, and filtered. The solvent was removed from the filtrate under a reduced pressure, and the resulting residue was refined by silica gel column chromatography (ethyl acetate : n-hexane = 1 : 3) to obtain 400 mg (yield 92%) of the title compound.

The synthetic route of 6940-76-7 has been constantly updated, and we look forward to future research findings.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 6940-76-7, name is 1-Chloro-3-iodopropane, A new synthetic method of this compound is introduced below., category: iodides-buliding-blocks

Solution stirred between -20 an’d 1 0 C for 30 min and subsequently cooled to -78 C. A solution of tert-butyl 6-chloropyridin-2-ylcarbamate (108; 57.0g, 0.249mol) in TH F (300mL) was added over 1 5 min. The reaction mixture was aged for 1 hour and then Cul (47.6g, 0.249mol) was added in one portion. The reaction mixture was al lowed to warm to – 1 0 C for one hour. 1 – Chloro-3-iodopropane (76.5g, 0.374 mol) was added neat over a period of 1 min, the cooling bath was removed and reaction allowed to warm to ambient temp and subsequently refluxed overnight. Upon completion of the reaction, the reaction mixture was cooled and quenched via addition of saturated sodium bicarbonate. The aqueous layer was extracted with EtOAc, The combined organic layers were dried over a2S04, filtered through a short si lica gel pad, concentrated to afford crude product., Triturated with ether to afforded tert-butyl 7-chloro-3,4- dihydro- l ,8-naphthyridine- l (2H)-carboxylate (109; 43g, yield 67%). M S (ESI) calcd for C,3H17C1N202 (m/z) 268.74.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
