Reaction Steps

To a solution of 36.6 g (0.3 mol) of 4-hydroxybenzaldehyde in 100 ml of ethanol were added dropwise, one after another, a solution of 12.0 g (0.3 mol) of sodium hydroxide in 100 ml of water and a solution of 36.5 ml of (0.307 mol) of benzylbromide in 100 ml of ethanol and the mixture was then kept for 1 hour at 50° C. The ethanol was extensively distilled off, finally in vacuo, the remaining aqueous emulsion was divided between water and ethyl acetate. The ethyl acetate phase was dried over sodium sulphate and evaporated down in vacuo. The residue remaining crystallised on trituration with petroleum ether and was recrystallised from diisopropylether. 48.0 g (75.4% of theory) of colourless crystals of melting point 118-122° C. were obtained.
