Procedure: A mixture containing 2.0 g of 3,5-dinitrocatechol in 5 ml of 2,6-dimethylbenzoylchloride was heated for 20 hours in 100° C. The excess 2,6-dimethylbenzoylchloride was removed in high vacuum. The residue was purified in silicagel column. Yield 1.5 g (45%), yellow viscous oil, which was crystallized from petroleum ether, m.p. 163°-165° C.
