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. 69034-08-8, name is 5-(Trifluoromethyl)pyrimidin-2-amine. A new synthetic method of this compound is introduced below., Computed Properties of C5H4F3N3

To a stirred solution of 5-(trifluoromethyl)pyrimidin-2-amine(A36, 4.5 g, 27.60 mmol) in l,4-dioxane(80 mL) was added 3-bromo-2-oxopropanoic acid(A15, 6.87 g , 41.4 mmol .The reaction mixture was heated at 100 C for 16 h. After completion of reaction mixture was concentrated under reduced pressure. The crude product was triturated with ethyl acetate and dried to afford 6-(trifluoromethyl)imidazo[l,2-a]pyrimidine-2-carboxylic acid A37 and A38 as dark brown mixture Yield: 7.0 g,(crude). LC-MS m/z : 229.96[M-H]

Here is a downstream synthesis route of the compound, Computed Properties of C5H4F3N3, blongs to pyrimidines compound. Computed Properties of C5H4F3N3

To a 20 ml glass vial was added (RS)-2-(4-bromo-3-fluoro-phenyl)-morpholine-4-carboxylic acid tert-butyl ester (200 mg, example 96(e)) and 5-trifluoromethyl-pyrimidin-2-ylamine (145 mg, CAS 69034-08-8) in dioxane (5 ml). The reaction mixture was purged with argon for 5 min. 2-Di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl (38.9 mg),tris(dibenzylideneacetone)dipalladium(0) (20.3 mg) and sodium tert-butoxide (59.9 mg) were then added. The vial was capped and heated at 120 C for 16 h. The reaction mixture was then filtered through sintered glass and the filtrate was concentrated in vacuo. The residue was purified by flash column chromatography (silica gel; gradient: 0% to 50% EtOAc in heptane) to afford (RS)-2-[3-fluoro-4-(5-trifluoromethyl-pyrimidin-2-ylamino)-phenyl]-morpholine-4- carboxylic acid tert-butyl ester (115 mg, 47%) as a yellow gum. MS (ISP): 441.4 ([M-H]”).
