The iodobenzamide neuroleptic analogue (S)-N-(1-ethylpyrrolidin-2-ylmethyl) -2-hydroxy-5-iodo-6-methoxybenzamide (5-IBZM) was synthesized stereospecifically and its pharmacological properties were compared with the 3-iodo isomer (IBZM) used for imaging D2 receptors in vivo. The isomer 5-IBZM had 100-fold lower affinity than IBZM and migrated with similar retention time as the byproduct formed during electrophilic iodination of BZM.

A series of substituted 6-methoxysalicylamides were synthesized from their corresponding 2,6-dimethoxybenzamides by demethylation of one methoxy group with boron tribromide. Substituted 6-methoxysalicylamides having a lipophilic aromatic substituent in the 3-position para with respect to the methoxy group, e.g. a bromo or an iodo atom or an ethyl or a propyl group, and having an (S)-N-(1-alkyl-2-pyrrolidinyl)methyl moiety as the side chain were found to be potent blockers of [3H]spiperone binding in vitro and potent inhibitors of the apomorphine syndrome in the rat. Similar to remoxipride but in contrast to haloperidol, some of the substituted salicylamides show a 10-20 fold separation between the dose that inhibits hyperactivity and that which inhibits stereotypy. It was concluded that, besides the requirement of a lipophilic substitutent in the position para to the methoxy group for antidopamine activity in vivo, the formation of a coplanar six-membered pseudoring involving the amide moiety and the methoxy group is a structural requirement for activity in vitro.
