A MICROWAVE ASSISTED ONE – POT SYNTHESIS OF TICLOPIDINE HYDROCHLORIDE THROUGH 4,5,6,7- TETRAHYDRO (3,2-C) THIENO PYRIDINE HYDROCHLORIDE
M. M. V. Ramana* and Rajesh K. Rao.
Abstract
The microwave assisted Pictet Spengler reaction of thiophene ethyl
amine and formaldehyde afforded 4,5,6,7-tetrahydro (3,2-c) thieno
pyridine hydrochloride (I), which was then subjected to alkylation with
2-chloro benzyl chloride under microwave conditions to afford
Ticlopidine Hydrochloride, thus making it one-pot, efficient and
economical approach.
Keywords: Ticlopidine Hydrochloride, Pictet-Spengler, Schiff base, Alkylation, Microwave.
