Participants

Reaction Steps

15 g. of the above-described ethyl α-(4-hydroxyphenyl)-α-(4-sulphoxyphenyl)-2-pyridine-acetate sodium salt were treated with 75 ml. acetic anhydride and 15 g. anhydrous sodium acetate for 18 hours at ambient temperature and then heated and stirred for 1 hour. The reaction mixture was filtered and the solution treated with excess diethyl ether to give an abundant precipitate. The product was filtered off and purified with ethanol-ether to give the desired ethyl α-(4-acetoxyphenyl)α-(4-sulphoxyphenyl)-2-pyridine-acetate sodium salt in the form of colourless crystals.
