By the reduction of anisaldehyde. Cannizzaro reacts with anise, formaldehyde and sodium hydroxide in ethanol to produce p-methoxybenzyl alcohol.

After the ethanol is recovered by distillation, the oil layer obtained by the reaction is extracted with benzene, acidified by adding acetic acid, and then neutralized with sodium bicarbonate to weakly alkaline. After washing with water to neutrality, the benzene is recovered by distillation, and the residue is subjected to vacuum distillation to obtain p-methoxy Benzyl alcohol.
