Anti-rheumatic agent (±)-epoxyquinomicin B was synthesized for a 22% overall yield in eight steps from commercially available 3-hydroxy-4- nitrobenzaldehyde via the intermediate quinone 6 prepared by selective phenol oxidation of 5 by use of Fremy's salt as the key step.

5-(tert-Butoxycarbonylaminoacetoxymethyl)-2-nitrophenoxyacetic acid was synthesized in seven steps starting from 5-methyl-2-nitrophenol. Its phenyl ester was selectively hydrolyzed with triethylamine in aqueous dioxane. 5-Hydroxymethyl-2-nitrophenoxyacetic acid was formed as by-product. Its formation was proved by independent synthesis from 1-acetoxy-5-bromomethyl-2-nitrobenzene. Experimental difficulties that arise along other routes to the target compound are discussed.
