4-Chlorobenzaldehyde → 1-(p-Chlorophenyl)-4-phenyl-7-(m-methylphenyl)-1,6-heptadien-3-one

Participants

Reaction Steps

A 20% sodium hydroxide solution (5 ml.) is added to a stirred solution of p-chlorobenzaldehyde(14 g., 0.1 mole) and 3-phenyl-6-(m-methylphenyl)-5-hexen-2-one (25.24 g., 0.096 mole) in ethanol (250 ml.). The yellowish solid that separates on continued stirring is collected, washed with cold ethanol, and air-dried, yield 34.9 g., m.p. 89°-93°C. Recrystallization from ethanaol produces material with m.p. 95°-98°C.
