Abstract
The present invention relates to the preparation of 2- (3-methyl-2-furoyl) -1,4,5-trimethyl-1,2,3,6-tetrahydropyridine of formula i by reaction between 2-cyano-1, 4,5-trimethyl-1,2,3,6-tetrahydropyridine and 3-furylmethylmagnesium chloride ** (formula) ** compound i is a new substance of possible interest as an analgesic and is prepared in accordance with process of the invention, by adding 2-cyano-1,4,5-trimethyl-1,2,3,6-tetrahydropyridine dissolved in ether onto an ethereal solution of freshly prepared 3-furylmethylmagnesium chloride. The reaction is carried out at room temperature during the addition of the 2-cyano-1,4,5-trimethyl-1,2,3,6-tetrahydropyridine and then at the reflux temperature.
