Abstract

The Michael addition reactions of indole to 4‐arylidene‐3‐methyl‐1‐phenyl‐5‐pyrazolone 1 were investigated in the solid state, by which a series of new compounds, 1‐aryl‐1‐(3‐indolyl)‐1‐(3′‐methyl‐1′‐phenyl‐5′‐pyrazolon‐4′‐yl)methanes 2, were easily obtained. This provides a feasible method of preparing novel compounds containing two heterocyclic groups at the same carbon.
