Process for the preparation of racemic ([2S[2R*[R[R*]]]]- and ([2R[2S*[S[S*]]]]-(±)- α,α' -[imino-bis(methylene)]bis[6-fluoro-chroman-2-methanol] of the compound of the formula (I) and its pure ([2S[2R*[R[R*]]]]- and ([2R[2S*[S[S*]]]]- enantiomer compounds characterized in that the products are prepared from 4--fluoro-phenole or 4-fluoro-anisole via crystalline, optically active intermediates.
