The reaction of 5-chloro-2-hydroxybenzaldehyde (I) with the chiral glycidyl tosylate (II) by means of K2CO3 in DMF gives the condensation product (III), which is oxidized with m-chloroperbenzoic acid to formyl ester (IV). The cyclization of (IV) with sodium methoxide in methanol affords the hydroxymethyl benzodioxane (V), which is tosylated with tosyl chloride in pyridine to the tosylate (VI). Finally, this compound is condensed with 1-(2-methoxyphenyl)piperidin-4-ylmethylamine (VII) by means of K2CO3 in refluxing acetonitrile.
