2-Amino-5-chlorobenzophenone 3 prepared in 2 steps from isatoic anhydride 1 on condensation with substituted benzoyl chlorides 6a-i in presence of Et 3N in 1,2-dichloroethane (DCE) affords substituted N-(2-benzoyl-4-chlorophenyl)-benzamides 7a-i which on reduction with NaBH 4 gives corresponding alcohols, N-[4-chloro-2-(α,α- hydroxyphenyl-methyl)phenyl]benzamides 8a-i. The structures of all the compounds are confirmed by 1H NMR spectra, and their cytokinin (plant growth promoting) activity is determined on seeds of Raphanus sativus, family Brassicaceae (common name white radish, variety Pusa Chetki), for concentrations varying between 0.1 to 10 mg/litre. Compounds 7c, 7d, 7g and 7h at all concentrations and 7i at 4 concentrations have been found to show higher plant growth promoting (PGP) activity than benzyladenine (standard). Compounds 8d and 8g also show moderate plant growth promoting (cytokinin) activity, while compounds 7a, 7b, 7e, 7f and 8a, 8b, 8c, 8e, 8f and 8i are found to have plant growth inhibiting (PGI) activity.

A study was carried out on the amination of 6-chloro-2-arylquinazolines.The reaction of p-chlorophenyl- and p-nitrophenyl derivatives gives a mixture of mono- and diamination products with predominance of the monoamino products.The desired diamine was also obtained in the reduction of 6-amino-2-(p-nitrophenyl)quinazoline.
