Procedure
By subjecting 7-amino-9-benzyloxy-2-(3-chloro-4-fluorobenzyl)-3,4-dihydro-2H-pyrido[1,2-a]pyrazine-1,8-dione (29 mg) obtained in Example 349, Step 2 to a reaction operation similar to that in Example 349, Steps 3 and 4 except that methanesulfonyl chloride was used instead of isobutyryl chloride, N-[2-(3-chloro-4-fluorobenzyl)-9-hydroxy-1,8-dioxo-1,3,4,8-tetrahydro-2H-pyrido[1,2-a]pyrazin-7-yl]methanesulfonamide (4.7 mg) was obtained.
