Procedure
2-Chlorobenzoyl chloride (23.0 mg, 0.291 mmol) was added to a mixture of 3-amino-7-hydroxy-2H-1-benzopyran-2-one (50.0 mg, 0.282 mmol), and the mixture was stirred at room temparature for 1 hour. 1N hydrochloric acid (10 ml) was added, and the mixture was stirred. The precipitated crystal was filtered and washed successively with water and diisopropyl ether to give the title compound as a light brown crystal (48.8 mg, 54.8%).
