According to the analysis of related databases, 14338-32-0, the application of this compound in the production field has become more and more popular.

Synthetic Route of 14338-32-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 14338-32-0, name is 2-Chloro-1-methylpyridinium iodide, molecular formula is C6H7ClIN, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

Step F: 2-[3-(Pyrrolidine-1-sulfonyl)-phenyl]-pent-4-enoic acid allyl-(1-(S)-phenyl-2-pyrrolidin-1-yl-ethyl)-amide To a stirred solution of allyl-(1-(S)-phenyl-2-pyrrolidin-1-yl-ethyl)-amine (1.00 g, 4.34 mmol) in dichloromethane (22 cm3) at ambient temperature was added 2-[3-(pyrrolidine-1-sulfonyl)-phenyl]-pent-4-enoic acid (1.34 g, 4.34 mmol) followed by 2-Chloro-1-methylpyridinium iodide (2.22 g, 8.68 mmol) and triethylamine (1.82 cm3, 13.0 mmol) to afford a yellow slurry. The mixture was stirred at ambient temperature for 44 hours to afford a brown solution. The solution was diluted with ethyl acetate (50 cm3) and poured into water (100 cm3). The aqueous was extracted with ethyl acetate (3*30 cm3) and the combined ethyl acetate extracts were washed with 1M sodium bicarbonate (2*50 cm3), brine (1*50 cm3), dried over sodium sulfate, vacuum filtered and the volatile fractions removed in vacuo to a crude brown oil. The crude product was purified by column chromatography (silica, eluding with dichloromethane-methanol 99:1 to 95:5 to afford the title compound as a tan viscous oil (2.10, 92.9%) with a positive ion ESI (M+H) +522.3.

According to the analysis of related databases, 14338-32-0, the application of this compound in the production field has become more and more popular.
