The reaction of methyl 5-bromoacetylsalicylate (I) with benzyl tert-butylamine (II) in methyl ethyl ketone gives methyl 5-(N-benzyl-N-tert-butyl-gycyl)salicylate (III), which is reduced with LiAlH4 in refluxing THF yielding alpha'-(N-benzyl-N-tert-butylami-nomethyl)-4-hydroxy-m-xylene-alpha,alpha'-diol (IV). Finally, this compound is debenzylated by hydrogenation with H2 over Pd/C in ethanol-water.
