Tropatepine (brand name Lepticur) is an anticholinergic used as an antiparkinsonian agent.

Synthesis

Tropatepine can be synthesized from 3-chlorotropane (1). A Grignard reaction between 3-chlorotropane and dibenzo[b,e]thiepin-11(6H)-one (2) followed by dehydration to the olefin produces tropatepine (3).
