反应详情

To a solution of benzofuran-3-yl acetate (8) (100 g, 1.42 mol) in methanol (350 mL) was added diluted (7.5%) H2SO4 (500 mL) at ambient temperature followed by heating to reflux for 1-3 h. The progress of the reaction was monitored by HPLC analysis. Upon completion of the reaction, the reaction mixture was cooled, filtered, and the slurry was washed with water, and vacuum dried to obtain the product meeting the desired specifications. Yield—83-100%.
