Procedure

Trimethylsilyl diazomethane (0.82 mL, 2.0 M in hexane) was added to a solution of {3-(3-nitrobenzyl)-7-dimethylcarbamoyloxy-2-oxo-2H-1-benzopyran-4-yl}acetic acid (compound 7f-1-1COOH) (350 mg, 0.82 mmol) in methanol (5.0 mL)/dichloromethane (8.0 mL), and the mixture was stirred at room temperature for 10 minutes. Aacetic acid (2.0 mL) was added to the reaction mixture, and the title compound (338 mg, 94%) was obtained by vacuum concentration as a pale yellow powder.
