Procedure
A mixture of 5-fluoroisatin (III, 0.803 g), acetic anhydride (0.546 g), dimethylaminopyridine (0.0059 g) and THF (25 ml) is stirred at 20°-25° for 1.25 hr. THF is then removed and dichloromethane is added. After standing, the crystals are collected and dried to give 5-fluoroisatin acetamide (IV).
