Reaction Steps

A mixture of 600 mg (2.8 mmol) of (E)-4-[2-(3-fluoro-phenyl)-vinyl]-phenylamine and 366 mg (2.8 mmol) of itaconic acid is heated to 130° C. After 1 hour, the molten material is cooled to RT and, thereafter, the resulting solid is triturated with ethyl acetate to yield 568 mg (62% of theory) of (RS)-(E)-1-{4-[2-(3-fluoro-phenyl)-vinyl]-phenyl}-5-oxo-pyrrolidine-3-carboxylic acid as a fine yellow powder; MS: m/e=324 (M−H)+.
