实验步骤: 12 g of 2-Benzyloxyphenol was dissolved in 300 ml of acetonitrile, 10.7 g of N-bromosuccinimide was added thereto, and the mixture was stirred at room temperature for 2 hours. Additional N-bromosuccinimide (1 g) was added thereto and the mixture was stirred for 1 hour, and further additional N-bromosuccinimide (1 g) was added thereto and the mixture was stirred for 2 hours. The reaction mixture was concentrated, and the residue was diluted with ethyl acetate and washed with water. The organic layer was dried over anhydrous magnesium sulfate and then filtered, and the filtrate was concentrated. The residue was purified by silica gel column chromatography, to give 14.927 g of the title compound in the 10:1 hexane-ethyl acetate fraction. the mixture was stirred for 1 hour the mixture was stirred for 2 hours The reaction mixture was concentrated the residue was diluted with ethyl acetate washed with water The organic layer was dried over anhydrous magnesium sulfate filtered the filtrate was concentrated The residue was purified by silica gel column chromatography
