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., HPLC of Formula: C3H6ClI
a) Preparation of 5-Chloro-2-(3.4-dimethoxyphenyl)-2-isopropylpentanenitrile 2-(3,4-dimethoxyphenyl)-3-methylbutanenitrile (1.21 g, 5.52 mmol) was added to a suspension of sodium amide (0.59 g, 14.4 mmol) in toluene (12 ml). The mixture was then heated to reflux for 2 hours before the addition of 1-chloro-3-iodopropane (0.9 ml, 8.3 mmol). The mixture was cooled to room temperature over 80 minutes, and worked up by addition of water. The product was extracted with methyl-t-butyl ether (MTBE). After usual work-up, including drying the organic extract using MgSO4 and concentrating under reduced pressure the product was purified on column chromatography eluding with (ethyl acetate: light petroleum (b.p. 40 -60 C.) =1:2), to give 1.4g (82% yield) of the required product.
The synthetic route of 6940-76-7 has been constantly updated, and we look forward to future research findings.
