Using a procedure analogous to Example 17, 1-{4-[1-(4-amino-3-methyl-phenyl)-1-ethyl-propyl]-2-methyl-phenoxy}-3,3-dimethyl-butan-2-one (229 mg, 0.6 mmol), ethanesulfonyl chloride (0.080 mL, 0.9 mmol) gives N-(4-{1-[4-(3,3-dimethyl-2-oxo-butoxy)-3-methyl-phenyl]-1-ethyl-propyl}-2-methyl-phenyl)-N,N-bis-ethanesulfonamide (Example 22) (120 mg, 35%), and N-(4-{1-[4-(3,3-Dimethyl-2-oxo-butoxy)-3-methyl-phenyl]-1-ethyl-propyl}-2-methyl-phenyl)-ethanesulfonamide (Example 23) (130 mg, 46%).
