Participants

Reaction Steps

(4-Hydroxy-2,3-dimethyl-phenyl)-acetic acid ethyl ester (45c) was prepared as described in Example 13. N-(2-Chloro-4-sulfamoyl-phenyl)-2-[4-(4-cyano-2-methyl-phenoxy)-2,3-dimethyl-phenyl]-acetamide (I-25) was prepared starting with 45c utilizing the procedure from example 1 except in step 1, 45c was used in place of 3-bromo-4-hydroxy-phenyl)-acetic acid ethyl ester and 3-methyl-4-fluoro-benzonitrile was used in place of 3-chloro-5-fluoro-benzonitrile and in step 4, 4-amino-3-chloro-benzenesulfonamide was used in place of 4-amino-benzenesulfonamide.
