Procedure

4-{[4-(5-Chloro-2-methoxy-benzenesulfonyl)-3,4-dihydro-2H-benzo[1,4]oxazine-6-carbonyl]-amino}-2-fluoro-benzoic acid, MS (ISP): m/e=519.0 (M−H), was prepared as described in example 1, steps 1 to 6. Step 5 was performed using 4-amino-2-fluoro-benzoic acid ethyl ester and yielded 4-{[4-(5-chloro-2-methoxy-benzenesulfonyl)-3,4-dihydro-2H-benzo[1,4]oxazine-6-carbonyl]-amino}-2-fluoro-benzoic acid ethyl ester, which was hydrolyzed in step 6.
