Procedure

The product of above-mentioned (a) (1.5 g, 6.7 mmol) was heated under reflux in acetic anhydride (10 ml) for 1 hr. The reaction solution was concentrated under reduced pressure, and the resulting residue was dissolved in 10% aqueous sodium hydroxide solution. The insoluble materials were collected by filtration, washed with water, and dried to give 0.31 g of the title compound.
