Participants

Reaction Steps

To 200 ml of benzene, 10.0 g (53.8 mmol) of 5-chloro-2-nitrobenzaldehyde (manufactured by Aldrich Chemical Co., Inc.) and 18.1 g (50.0 mmol) of Wittig reagent (carbethoxyethylidene triphenylphosphorane, manufactured by Aldrich Chemical Co., Inc.) were added, and the mixture m was stirred at room temperature for one night. After the completion of the reaction was verified by TLC, the reaction liquid was concentrated, whereby a crude product was obtained. This crude product was refined by a column chromatography (aminopropyl-modified silica gel (Fuji Silysia Chem. Co., NH-DM); developing agent: hexane/ethyl acetate=1/1), whereby 13.3 g of the aimed compound were obtained as a crystal (yield: 98%).
