New syntheses of wopelletierine and its N-methyl derivative have been provided by Wibaut et a . " " by an extension of the process used for the preparation of di-pelletierine acetal. By the action of acetic anhydride on lithium picolyl in nitrogen, an acetyl group was inserted in the methyl group of a-picoline and the resulting -2-pyridylpropane-/S-one (a-picolyl methyl ketone), C5H4N. CHg. CO. CH3, b.p. 92°/l-5 nun., characterised as the picrate, m.p. 140-140-5°, and picrolonate, m.p. 179-5-181°, was hydrogenated in acetic acid with platinie oxide as catalyst, to dl-isopelletierine, C5H10N. CHj. CO. CH3, b.p. 62°/0-8 mm., identified as the picrate, m.p. 147-5-148-5°, and picrolonate, m.p. 177-9°.
