摘要

A process for the preparation of 1- (2-furyl) -1- (1,4-dimethyl-1,2,3,6-tetrahydro-2-pyridyl) -ethane of formula i (* see formula i) characterized because in a first stage of the process, 2- (2-furoyl) -1,4-dimethyl-1,2,3,6-tetrahydropyridine with an excess of methylmagnesium iodide are reacted in ethereal solution at reflux temperature., which, after hydrolyzing and extracting with an organic solvent, gives erythro 1-2 (2-furyl) -1- (1,4-dimethyl-1,2,3,6-tetrahydro-2-pyridyl) -ethane of formula ii (* see formula ii).
