Related Products of 112110-07-3, 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. 112110-07-3, name is 5-(Trifluoromethyl)pyridin-3-amine. A new synthetic method of this compound is introduced below.
To a mixture of 2-[2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]acetic acid (34, 0.899 g, 3.21 mmol) in ethyl acetate (20 ml) was added 5-(trifluoromethyl)pyridin-3-amine (10, 0.520 g, 3.21 mmol), triethylamine (1.0 ml) and propylphosphonic anhydride (50 wt % solution in ethyl acetate, 2.51 ml, 4.22 mmol). The mixture was allowed to stir at room temperature for 2 hours. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was washed with water and brine, and then dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was suspended in a mixture of ethyl acetate and hexane. The solid precipitate was collected by filtration and washed with hexane. After drying, this provided 1.03 g of compound 46. MS ESI [M+H+]+=425.2.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,112110-07-3, 5-(Trifluoromethyl)pyridin-3-amine, and friends who are interested can also refer to it.
