Abstract

PURPOSE: To obtain the titled substance in high yield from an inexpensive raw material without using toxic substances, by reducting meta-haloacetophenone, dehydrating the reduction product into a meta-halostyrene, reacting the meta- halostyrene with Mg and subsequently benzonitrile, and hydrolyzing the reaction product.
CONSTITUTION: A meta-haloacetophenone is educed by metal hydride or hydrogen in the presence of a catalyst, etc., to be converted into an α-(m-halophenyl) ethyl alcohol, which is dehydrated in the vapor or liquid phase, to give a meta-halostyrene. Subsequently, the meta-halostyrene is reacted with metallic Mg, to be converted into a meta-vinylphenyl magnesium halide, which is reacted with benzonitrile, and then hydrolyzed, to give the titled substance.
EFFECT: Economical due to the saved trouble of waste liquor treatment or product purification in the absence of inorganic cyanides.
USE: An anti-inflammatory agent. Raw material for α-(m-benzoylphenyl)propionic acid which is an anti-inflammatory analgesic and antipyretic agent.
