Indriline is a central nervous system stimulant with antidepressant activity and application in the treatment of gastric ulcers.

A patent using this chemical is assigned to Pharmacol.[1][2]

Synthesis

The chemical synthesis of indriline has been described:[3][4]

Indriline synthesis
Indriline synthesis

Treatment of 3-phenylindene [1961-97-3] (1) with n-butyl lithium and dimethylamino-2-choroethane gave indriline as well as some inactive isomer. Based on neighboring group participation (NGP), the reaction intermediate is presumably an aziridinium ion[4]

According to Molbase the number of routes for preparing the starting 3-phenylindene is rich. For example from dihydrochalcone.[5] A more classical synthesis is also described in a Pyrophendane patent.
