The target compound-alibendol(Ⅰ) was prepared via allylation, oxida-tion with NaClO2 and NH2SO3H, esterification，Claisen rearrangement and ami-nolysis reaction from 2-hydroxy-3-methoxybenzaldehyde. The yield is 71.9% in the overall five steps. Some intermediates and target product were identified by 1H NMR and MS.
