POTENTIAL NEUROLEPTICS OF THE ORTHOPRAMIDE SERIES; SYNTHESIS OF HETEROCYCLIC 5-AMINO-2-METHOXYBENZAMIDES AND OF SOME RELATED COMPOUNDS

2-Methoxy-5-nitrobenzoyl chloride was reacted with 2-(aminoethyl)-1-ethylpyrrolidine, 3-amino-1-ethylpiperidine, 4-amino-1-benzylpiperidine, 1-benzylpiperazine, and 1-amino-4-benzylpiperazine and gave the N-substituted 2-methoxy-5-nitrobenzamides VIa-VIe.Their reduction with hydrazine hydrate and Raney nickel in ethanol afforded the corresponding 5-amino-2-methoxybenzamides VIIa-VIIe.The amino amides VIIb and VIIc were transformed to methylamino compounds XIb and XIc via the 4-toluenesulfonamides VIIIb and VIIIc and the N-methyl-4-toluenesulfonamides Xb and Xc.The N-(1-benzyl-4-piperidinyl)amides VIc, VIIc, and XIc were found to be mild neuroleptics having antiapomorphine, some cataleptic and some ataxic activity.

Synthesis and Neuroleptic Activity of N--2-methoxy-5-sulfonamidobenzamides

A series of some novel N-benzamides involving replacement of the sulfamoyl group in sulpiride with a sulfonamido group was synthesized and tested for dopamine receptor blockade.In comparison with sulpiride, several compounds were considerably more potent than sulpiride as dopamine receptor blockers.The structure-activity relationships are discussed.
