Application of 30041-95-3, These common heterocyclic compound, 30041-95-3, name is Ethyl 2-(4-cyanophenoxy)acetate, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: B(C6F5)3 (67.3 mg, 0.13 mmol, 5 mol %) was added to a stirred solution of 3,4-dichlorobenzaldehyde (172 mg, 1 mmol) and NaN3 (97.5 mg, 1.5 mmol) in DMF (5 mL) and was heated at 120 C. After completion of reaction (as monitored by TLC), the reaction mixture was cooled to room temperature and was added 5 mL of cold water followed by 10 mL of 2 N HCl and 10 mL of ethyl acetate. The resulting mixture was stirred vigorously for 15 min. The organic layer was separated and aqueous layer was again extracted with ethyl acetate (3 ¡Á 15 mL). The combined organic layer was washed with water and dried over anhydrous sodium sulfate and was evaporated under reduced pressure. The crude product was purified by column chromatography (silica gel, EtOAc/hexane 9:1) to obtain pure 5-(3,4-dichlorophenyl)-1H-tetrazole. The known compounds were characterized and confirmed by comparison of their spectral data and physical properties with reported literature.
Statistics shows that Ethyl 2-(4-cyanophenoxy)acetate is playing an increasingly important role. we look forward to future research findings about 30041-95-3.
