반응 단계

By the procedure of Example 38, benzthiazole (2.7 g., 0.02 moles) was converted to its 2-lithio derivative and then reacted with anhydrous alloxan to yield title product, initially isolated as an oil. The latter was crystallized from ether-hexane [2.2 g.; Rf 0.55 (1:1 ethyl acetate:hexane/5% acetic acid)].
