Reaction Steps

To a stirred suspension of 2.0090 g. (9.122 mM) of 4-methyl-1-oxo-1H-2-benzothiopyran-3-carboxylic acid in 50 ml. of distilled water is added 0.7663 g. (9.122 mM) of sodium bicarbonate. After stirring at room temperature for 1.5 hours, the solution is filtered and the filtrate freeze-dried to give sodium 4-methyl-1-oxo-1H-2-benzothiopyran-3-carboxylate, m.p. 330° (dec.).
