Reaction Steps
48.0 g of 4-bromo-1,2-benzenediol [cf. W. Rosermund, Ber. 62, 1262 and so forth (1923)] are oxidatively condensed with 33.4 g of the sodium salt of benzenesulphinic acid in a manner analogous to that described in Example 5a). Crystallisation from 1,2-dichloroethane yields 4-bromo-5-(phenylsulphonyl)-1,2-benzenediol in the form of colourless crystals having a melting point of 166°-168°.
