Reaction Steps

To 20 ml of methylene chloride, 1.29 g (3.68 mmol) of 5-formyl-2-[(4-chlorophenyl)sulfonylaminomethyl]indan and 1.28 g (3.68 mmol) of carboethoxymethylene triphenylphosphoran were added and stirred for 16 hours at room temperature. The reaction solution was purified by silica gel column chromatography.(chloroform), and the precipitates obtained were recrystallized from a solvent mixture of ethyl acetate and hexane. 1.18 g of colorless crystals were obtained. Yield: 77%
