Reaction Steps
To a stirred suspension of 2.0347 g. (8.613 mM) of 7-methoxy-1-oxo-1H-2-benzothiopyran-3-carboxylic acid in 50 ml. of distilled water is added 0.7236 g. (8.613 mM) of sodium bicarbonate. The resulting mixture is stirred at 25°-35° for 1.25 hours, filtered, and the filtrate freezedried to give sodium 7-methoxy-1-oxo-1H-2-benzothiopyran-3-carboxylate as a pale yellow solid, m.p. >350°.
