4-Hydroxybenzaldehyde → (-)-N-(p-hydroxybenzylidene)-1-(p-bromophenyl)ethylamine

Participants

Reaction Steps

4.44 g (0.0222 mole) of (R)-(+)-1-(p-bromophenyl)ethylamine and 2.85 g (0.0233 mole) of p-hydroxybenzaldehyde were dissolved in 30 ml of ethyl alcohol, and the solution thus formed was stirred under reflux for 3 hours. After the completion of the reaction, the reaction mixture was concentrated under reduced pressure, and refined by a column chromatography using 30 g of silica gel to give 6.75 g of (-)-N-(p-hydroxybenzylidene)-1-(p-bromophenyl)ethylamine.
