Abstract

Selon l'invention, on fait réagir le chlorure de 3-benzo-Øbõthiénylméthylmagnésium, obtenu à l'état fortement dilué et en atmosphère inerte, avec l'iodure de 1,4-diméthylpyridinium dans l'éther anhydre maintenu à la température de reflux, ce qui donne la 2-3(3-benzoØbõthiénylméthyl)-1,4-diméthyl-1,2-dihydropyridine intermédiaire que l'on fait réagir, sans purification ultérieure, en milieu basique, par exemple dans l'hydroxyde de sodium, avec le borohydrure de sodium en solution hydrométhanolique, ce qui conduit à un mélange de 2-(3-benzoØbõthiénylméthyl)-l,4-diméthyl-1,2,3,6-tétrahydro-pyridine et de 2-3(benzoØbõthiénylméthyl)-1,4-diméthyl-1,2,5,6-tétrahydro-pyridine que l'on sépare par cristallisation fractionnée des picrates, et on chauffe le mélange des tétrahydropyridines II et II à 135 degrés C, dans un acide inorganique fort, par exemple l'acide bromhydrique à 48 %, pour obtenir le 2,5-diméthyl-benzoØbõthiénolØ2,3-fõmorphane.
