A PROCESS FOR THE SYNTHESIS OF (E) -2-[1 - (4 - METHYL PHENYL) -3-(1-PYRRONYL)-1 - PROPENYL] PYRIDINE (TRIPROLIDINE)

摘要

A Process for the synthesis of (E) - 2 - [1 - (4 - methyl phenyl) -3- (1- pyrrolidinyl)-l- propenyl] pyridine (TRIPROLIDINE) by reacting 2-(l-pyrrolidino)ethyl triphenyl phosphonium bromide with 2-(p-toluoyl) pyridine in presence of aprotic solvent and a base, isomeising in presence of acid catalyst.
