Procedure
Benzenesulfonyl chloride (4.0 g, 22.8 mmol) was added to a solution of 3-acetylamino-2-oxo-8-hydroxychromen (5.0 g, 22.8 mmol) in pyridine (50 mL) followed by stirring for one night. Chloroform (100 mL) was added thereto and crystals were filtered therefrom and washed with hexane. The crystals were dried to give 7.0 g (85%) of the title compound.
