Parekh, Hansa published the artcilePreparation and resolution of (+-)-p-(α-cyanoarylamino)benzoic acid, Synthetic Route of 13312-84-0, the publication is Indian Journal of Chemistry (1973), 11(5), 501-3, database is CAplus.
α-Amino nitriles (±)-RCH(CN)NHC6H4COOH-p [(±)I:R = Ph, o-ClC6H4, p-MeOC6H4] were prepared by condensing an aldehyde cyanhydrin with p-aminobenzoic acid. The resolution of (±)(I) into optical isomers was accomplished through fractional crystallization of the brucine salts to give the resp. (-)-nitriles. With (±)-I (R = p-MeOC6H4), the (+)-nitrile was also obtained. The introduction of Cl in the Ph nucleus at the ortho-position enhanced the optical activity, while the MeO group at the paraposition decreased the optical activity.
