Description
The major constituent of Kopsia !ruticosa, this base has [α]D - 17.5° (c 2.15, CHC13). It forms a series of crystalline salts and derivatives, e.g. the aurichloride, m.p. 203-5°C (dec.); perchlorate, m.p. 284°C (dec.); picrate, m.p. 230°C (dec.) and methiodide, m.p. 200°C (dec.). It may be reduced to the dihydro derivative which has m.p. 218°C. When fused with NaOH the alkaloid furnishes 2- methylindole and 2-indole-2-carboxylic acid.
