Reaktionsschritte

A solution composed of 5.0 g of 1,2,4-trihydroxybenzene, 9.7 g of triethyl orthoacetate and 50 ml of toluene-carbon tetrachloride (1:1) was refluxed for 1.5 hours. The solvent was evaporated, and the residue was purified by column chromatography to give 6.7 g (yield 86%) of the desired product as pale brown crystals having a melting point of 86° to 87° C.
