1805-32-9, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 1805-32-9 as follows.
General procedure: Cu/OMS-2 (10 mg, 0.25 mol%), benzyl alcohol (2 mmol), N-arylamidine (0.5 mmol), toluene (2 mL) were added to a flask with a bar. The flask was stirred at 90 C for 20 h under air. After cooling to room temperature, the mixture was diluted with ethyl acetate and filtered. The filtrate was removed under reduced pressure to get the crude product, which was further purified by silica gel chromatography (petroleum/ethyl acetate = 40/1-50/1 as eluent) to yield corresponding product. The identity and purity of the products were confirmedby 1H, 13C NMR spectroscopic and HRMS analysis.
The chemical industry reduces the impact on the environment during synthesis 1805-32-9, I believe this compound will play a more active role in future production and life.
