Reaction Steps
4-{[4-(3-Difluoromethoxy-benzenesulfonyl)-3,4-dihydro-2H-benzo[1,4]oxazine-6-carbonyl]-amino}-benzoic acid, MS (ISP): m/e=502.9 (M−H), was prepared as described for example 14, steps 1 to 8. Step 7 was performed using 3-difluoromethoxy-benzenesulfonyl chloride and yielded 4-{[4-(3-difluoromethoxy-benzenesulfonyl)-3,4-dihydro-2H-benzo[1,4]oxazine-6-carbonyl]-amino}-benzoic acid ethyl ester, which was hydrolyzed in step 8.
