摘要：

A series of 2-substituted 4H-3, 1-benzoxazine-4-ones were synthesized from N-acyl anthranilic acid in the presence molten tetraethylammonium chloride as an ionic liquid under microwave irradiation. The advantages of this procedure is the employment of Mg(HSO4)(2), a dehydrating agent as a catalyst instead of acetic anhydride, shorter reaction time, easy workup and high yield of the products.
