实验步骤: Into a solution of 2 g of 7-hydroxy-4-methyl-1-indanone in 10 ml of dichloroethane was added 2.27 g of 1-piperidine sulfonyl chloride. Then 10 g of anhydrous aluminum chloride was gradually added to the mixture and stirred, and the reaction mixture was refluxed by heating for 8 hours. The reaction mixture was extracted with 200 ml of chloroform, washed with water, then the chloroform was removed by evaporation under a reduced pressure. The residue was purified by means of a silica gel column chromatography (eluent: chloroform), and recrystallized from ethanol to obtain 1.24 g of 7-hydroxy-4-methyl-6-(1-piperidinesulfonyl)-1-indanone. the reaction mixture was refluxed by heating for 8 hours The reaction mixture was extracted with 200 ml of chloroform washed with water the chloroform was removed by evaporation under a reduced pressure The residue was purified by means of a silica gel column chromatography (eluent: chloroform) recrystallized from ethanol
