Patent ID: 8067647

Claim:
A method for producing a β-nitrostyrene compound by condensing a benzaldehyde derivative represented by the following formula (I): (in formula (I), n represents an integer of 0 to 3, and n Rs may be identical or different and each may represent a halogen atom, an alkyl group, a hydroxyl group, an alkoxy group, a haloalkyl group, or a cycloalkyloxy group, or when n represents 2 or 3, two Rs may together form an alkylenedioxy group) and nitromethane in an acetic acid solvent in a presence of a primary amine, said β-nitrostyrene compound being represented by the following formula (II): (in formula (II), n and R are as set forth above), wherein said condensing is performed at a reaction temperature of 30 to 80° C.
