Application of 941685-26-3, 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. 941685-26-3, name is 4-Chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine. A new synthetic method of this compound is introduced below.
233 mg (0. 82mmo 1) 2- [(4-chloropyrrolo [2,3 -d]pyrimidin-7-yl)methoxy] ethyl-trimethylsilane was dissolved in 4 ml dry THF and cooled down to -78 C and 500 jiL (1.8 M stocksolution, 0.9 mmol, 1.1 eq.) LDA was added. The mixture was stirred under nitrogen for40 minutes at -78 C then 208 mg iodine (0.82 mmol, 1 eq.) was added and allowed to warm to r.t. It was stirred for 40 minutes, then water was added. The solution was extracted with EEO (2 x 15 ml), combined organic phase was dried (magnesium sulfate) and evaporated. The residue was purified by flash chromatography (Eluent: heptane-EEOgradient).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,941685-26-3, 4-Chloro-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine, and friends who are interested can also refer to it.
