Ipsapirone is a selective 5-HT1A receptor partial agonist of the piperazine and azapirone chemical classes.[1] It has antidepressant and anxiolytic effects.[1] Ipsapirone was studied in several placebo-controlled trials for depression and continues to be used in research.[2]

Synthesis

Note that this is a homologue of Revospirone differing only in respect of the length of the sidehain.

Synthesis:[6] Patent (Ex 7):[7]

The alkylation of Saccharin [81-07-2] (1) with tetramethylenedibromide [110-52-1] (2) gives N-bromobutylsaccharin [103564-59-6] (3). Alkylation of this with 2-(1-Piperazinyl)pyrimidine [20980-22-7] (4) yields Ipsapirone (5).
