Yield: 89%

Reaction Conditions:

with pyridine in ethanolReflux;Knoevenagel Condensation;

Steps:

Synthesis of 2-((1H-pyrrol-2-yl)methylene)-1H-indene-1,3(2H)-dione (PP6)
Indane-1,3-dione (6.50 g, 44.47 mmol, M = 146.14 g/mol) and 1H-pyrrole-2-carbaldehyde (4.22 g, 44.47mmol, M = 95.10 g/mol) were dissolved in ethanol (50 mL) and a few drops of pyridine were added.The solution was heated at reflux overnight, providing a precipitate. After cooling, it was filtered off,washed several times with ethanol and pentane, and dried under vacuum. The reaction product wasidentified as bindone, the product resulting from the self-condensation of indane-1,3-dione (5.43 g,89% yield, grey solid).
