Benzene → HCID 70216990, compound

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 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%).
