Related Products of 349-75-7, 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. 349-75-7, name is (3-(Trifluoromethyl)phenyl)methanol. A new synthetic method of this compound is introduced below.
General procedure: To a solutionof a carboxylic acid in dry DMF (0.2±1.6 mL), CDI (2±2.2 equiv) was added and the mixturewas stirred at rt for 1 h under argon atmosphere. An alcohol (1.1±2 equiv), DBU (0.5±2 equiv)and DMAP (0.1 equiv) were subsequently added and the reaction mixture was microwave irradiatedat 50 C for 1 h. The reaction was quenched with ice water and extracted with EtOAc.The combined organic layers were washed with a saturated solution of NaHCO3 in water,brine and the solvent was evaporated under reduced pressure at 40 C. The crude residue waspurified by flash column chromatography with appropriate eluents and a gradient.3-(trifluoromethyl)benzyl 2-[(4-methoxyphenoxy)methyl]-5-methyl-6-[[3-(trifluoromethyl)benzyl]oxy]pyrimidine-4-carboxylate (21). General procedure IV was followed.Compound 16 (0.060 g, 0.13 mmol), dry DMF (0.2 mL), CDI (43 mg, 0.27 mmol, 2 equiv), 3-(trifluoromethyl)benzyl alcohol (36 muL, 0.27 mmol, 2 equiv), DBU (0.010 mL, 0.067 mmol, 0.5equiv), DMAP (1.6 mg, 0.013 mmol, 0.1 equiv). Flash chromatography eluents: cyclohexane(A), EtOAc (B); gradient: 6%45% B×10 CV. Compound 21 was isolated as a yellow oil (49mg, 0.081 mmol, 62% yield).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,349-75-7, (3-(Trifluoromethyl)phenyl)methanol, and friends who are interested can also refer to it.
