실험 절차

A solution of 2-anilino-6,7-dimethyl-1,4naphthoquinone (3.1; 0.014 mole) in concentrated sulphuric acid (70ml) was diluted with an equal volume of water and refluxed for 1 minute. After pouring into cold water the precipitated hydroxy derivative was filtered off and extracted into petrol ether (b.p. 100°-102° C). After treatment of the extract with charcoal the title compound separated as a yellow solid, 1.29g (55%), m.p. 175°-177° C (d). (Found; C, 71.29; H, 5.07 C12H10O3 requires; C, 71.28; H, 4.98%)
