Another synthetic route involved preparation of a 2-(2-thienyl)ethanol, its conversion to 2-(2-thienyl)ethyl paratoluene sulfonate and benzylation with o-chlorobenzylamine to give N-(2-chloro-benzyl)-2-(2-thienyl)ethylamine hydrochloride, which is cyclized to give ticlopidine free base, as described by Braye in U.S. Pat. No. 4,127,580.
