Brief introduction of 35700-40-4

35700-40-4, As the paragraph descriping shows that 35700-40-4 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.35700-40-4,2,3-Dihydrobenzofuran-7-carboxylic acid,as a common compound, the synthetic route is as follows.

1M Borane-THF complex THF solution (193 mL, 193.35 mmol) was slowly added to a solution of 2,3-dihydrobenzofuran-7-carboxylic acid (10.58 g, 64.45 mmol) in THF (65 mL) over 30 min while the reaction solution was maintained at room temperature. The reaction mixture was stirred at 60C for 3.5 hr, and poured into ice (about 400 g). The mixture was stirred at room temperature for 30 min, and extracted three times with ethyl acetate. The organic layer was washed with aqueous sodium hydrogen carbonate solution and brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure to give (2,3-dihydrobenzofuran-7-yl)methanol (9.76 g, 65.0 mmol, quant.) as a colorless oil.
