This compound, also called tienilic acid, is a diuretic and uricosuric agent used in therapy. It is obtained in the very pure state in a single operation by oxidising a compound of formula I, in which Z is a -CH2OH, -CHOH-CH2OH or -CHO group, by means of an inorganic oxidising agent in a solvent at a temperature from -15 to 75 DEG C. The oxidising agent can be potassium permanganate, potassium chromate or sodium periodate. <IMAGE>
