-
, (2019/01/15)
Processes are disclosed for making vortioxetine and pharmaceutically acceptable salts thereof. A propylene glycol solvate of vortioxetine hydrobromide is disclosed. A novel crystalline form of vortioxetine hydrobromide propylene glycol solvate, designated form AC1, is disclosed along with a method for making same. Form AC1 may be characterized by an x-ray powder diffraction pattern with peaks at about 19.64, 22.85, 25.51, 29.57, 30.18±0.2 degrees 2-theta.

Mechanism and Scope of Base-Controlled Catalyst-Free N-Arylation of Amines with Unactivated Fluorobenzenes

, p. 846 - 851 (2017/02/05)
A general method for transition metal-free N-arylation of amines has been developed. Mechanistic studies have revealed that the ability of the base to facilitate the desired amination without promoting unwanted side reactions is the guiding factor. By employing lithium bis(trimethylsilyl)amide as a base the resultant deprotonated amines readily react with a range of unactivated fluorobenzene derivatives. This new arylation method is utilized for the simple two-step synthesis of the antidepressant Vortioxetine.
