Ethyl -4-hydroxy-2-methyl- (6a), and -2,3,5-trimethyl-benzoate (6b), together with ethyl 4-hydroxy-2,3-dimethylbenzoate (6c), have been prepared in satisfactory yields by deoxygenation of the corresponding resorcylate esters, (5a-c), respectively, via hydrogenolysis of their 4-benzyloxy-2-(1-phenyl-1H-tetrazolyloxy)-derivatives, (8a-c).Ethyl 2,4-dihydroxy-5,6-dimethyl-3-trideuterio-methylbenzoate (5d) has been synthesised by trideuteriomethylation of ethyl 2,3-dimethyl-4,6-dioxocyclohexanecarboxylate (10c), followed by dehydrogenation.Preparation of the requisite resorcylate derivatives are included.
