Reaction Steps

The title compound was prepared from 2-chlorobenzimidazole and 2,2-bis(4-fluorophenyl)ethylamine (prepared by Procedure B from 2,2-bis(4-fluoro-phenyl)acetaldehyde) by Procedure A (20 min at 170° C.). The product was isolated by preparative LCMS to give the title compound as the free base (white solid, mp 155-157° C.).
