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. 17325-26-7, name is Methyl 1H-imidazole-5-carboxylate, A new synthetic method of this compound is introduced below., SDS of cas: 17325-26-7
(1) To a solution of methyl 4-imidazole carboxylate (a-1) (5.0 g, 39 mmol) in tetrahydrofuran (THF) (100 mL), p-trifluoromethyl benzyl alcohol (a-2) (6.5 mL, 48 mmol) and triphenylphosphine (PPh3) (12 g, 47 mmol) were added and after adding a toluene solution (25 mL, 48 mmol) of 1.9 mol/L diisopropyl azodicarboxylate (DIAD) dropwise, the resulting mixture was stirred at room temperature for 3 hours. After distilling off the solvents under reduced pressure, the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=50:500:100) and purified again by silica gel (NH) column chromatography (n-hexane:ethyl acetate=90:1050:50) to give methyl 1-[4-(trifluoromethyl)benzyl]-1H-imidazole-5-carboxylate (a-3) (amount, 7.7 g; yield, 69%).
The synthetic route of 17325-26-7 has been constantly updated, and we look forward to future research findings.
