Procedure

To a stirred suspension of 1.6345 g. (6.915 mM) of the carboxylic acid of Example 5 in 50 ml. of distilled water is added 0.5809 g. (6.915 mM) of sodium bicarbonate. After stirring at 25° for 2 hours, the solution is filtered and freeze-dried to give sodium 6-methoxy-1-oxo-1H-2-benzothiopyran- 3-carboxylate as a white solid, m.p. >360°.
