Thermolysis of 2-[3-methyl-α-(4-pyridyl)vinyl]indole (6a) at 500 °C for 3 min gave 11-demethylellipticine (7a). The similar reaction by using 2-[2,3-dimethyl-α-(4-pyridyl)vinyl]indole (6b) afforded olivacine (7b). Ellipticine and 11-demethylellipticine were obtained by thermolysis of 2-[3-ethyl-α-(4-pyridyl)vinyl]indole (6c).
