496-16-2, 2,3-Dihydrobenzo[b]furan is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
56 g (0.42 mol) of aluminum trichloride is added to 280 g of methylene chloride,Cool to 0¡ãC,Temperature drop below 10¡ãC45 g (0.33 mol) monoethyl oxalyl chloride,After the drop, the heat preservation reaction is 1hr,36 g (0.30 mol) of 2,3-dihydrobenzofuran (Compound 3) was added dropwise below 10¡ã C., and the reaction was allowed to proceed overnight at room temperature.After confirming the reaction,The reaction solution was poured into 300 g of ice water,Stirring liquid,Extract with dichloromethane (100g x 2)Combine the organic phase,Wash once with 200 g of saturated aqueous sodium bicarbonate,filter,The filtrate was dried over anhydrous sodium sulfate.Filtered,Concentrate to give about 73 g of oil (theoretical amount: 65.98 g).
496-16-2, As the paragraph descriping shows that 496-16-2 is playing an increasingly important role.
