• 説明

  An alkaloid which occurs in Tabernaemontana psychotrifolia H.B.K., this base is laevorotatory having [α]>_D - 243° and gives an ultraviolet spectrum with absorption maxima at 222, 2S0 and 296 mp. with a shoulder at 272 mil. The alkaloid may be purified by recrystallization from Me2CO followed by sublima_x0002_tion. It yields a crystalline methiodide, m.p. 272-4°C (dec.) which has an ultraviolet spectrum containing an absorption maximum at 222 mp. and a shoulder at 276 mp.. On catalytic hydrogenation with Pt02 as catalyst it gives the dihydro derivative, m.p. 191-3°C, furnishing a methiodide, m.p. 265-SoC (dec.). Zn dust distillation yields 3-ethylpyridine and 3-methyl-5-ethylpyridine.
