IB503 is a tricyclic antidepressant drug with antimanic effect. It is an analog of amitriptyline and dothiepine (dosulepin).[1][2][3][4][5]
It uses a thiophene surrogate of dibenzosuberane ring. Pizotifen also uses the same surrogate moiety and the same precursor. Pizotifen is an analog of Cyproheptadine.
See also: Pipethiadene and Bisulepin.
Synthesis
A Grignard reaction between 9,10-Dihydro-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-4-one [1622-55-5] gives a carbinol, which is dehydrated to IB 503.
