Procedure

To a solution of 2-(7-fluoro-2H-1,4-benzoxazin-3(4H)-on-6-yl)-4,5,6,7-tetrahydro-1,2,3-benzotriazole-1-oxide (0.5 g) in dimethylformamide (5 ml), sodium hydride (0.1 g) and then ethyl iodide (0.3 g) were added, followed by heating at 40° C. for 2 hours. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration, dried and recrystallized from a mixture of acetonitrile and isopropanol (1:10) to give Compound No. 2 (0.4 g). m.p., 143°-144° C.
