Procedure

To a solution of 3-chloro-2-[7-fluoro-2H-1,4-benzoxazin-3(4H)-on-6-yl]-4,5,6,7-tetrahydro-2H-indazole (1.0 g) in N,N-dimethylformamide (10 ml), sodium hydride (0.3 g) and ethyl iodide (0.5 g) were successively added, and the resultant mixture was heated at 50° to 60° C., followed by stirring for 3 hours. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration and purified by silica gel column chromatography using a mixture of ethyl acetate and hexane as an eluent to give Compound No. 1 (0.9 g), m.p., 101.5°-102.5° C.
