US 4,055,592 A · N-(Sulfo-lower alkyl) amides of (3-trifluoromethylphenoxy) (4-chlorophenyl)acetic acid

Abstract

N-(Sulfo-lower alkyl)amides of (3-trifluoromethylphenoxy)-(4-chlorophenyl)acetic acid which are useful in the treatment of atherosclerosis. The N-(sulfo-lower alkyl)amides of (3-trifluoromethylphenoxy) (4-chlorophenyl)-acetic acid are prepared by reacting a (3-trifluoromethylphenoxy) (4-chlorophenyl)acetyl halide with an amino-lower alkanesulfonic acid.
