Procedure

The product of above-mentioned (b) (0.28 g, 1.4 mmol) was heated under reflux in acetic anhydride (6.7 ml) overnight. The reaction solution was poured into ice-cold water, and the precipitated crystals were collected by filtration, washed with water, followed by drying to give 0.25 g of the title compound.
