The invention relates to 1-(3-sulfonylphenyl)-3-(cyclopent-2-en-1-yl)urea derivatives, and their use in treating or preventing diseases and conditions mediated by the CXCR2 receptor In addition, the invention relates to compositions containing the derivatives and processes for their preparation. ##STR00001##

The invention relates to the field of organic chemistry and medicine, and more particularly to a method of producing synthetic biologically active derivatives of carbopentoxysulfanilic acid. The present method of producing a sodium salt of (2,6-dichlorophenyl)amide carbopentoxysulfanilic acid is characterized in that the reaction mass formed during the production of (2,6-dichlorophenyl)amide carbopentoxysulfanilic acid is agitated in a medium which is acidified with a solution of hydrochloric acid to pH 5-5.5, and the isolated precipitate may be washed with water acidified with a solution of hydrochloric acid to pH 5-5.5. This increases the yield of a sodium salt of (2,6-dichlorophenyl)amide carbopentoxysulfanilic acid to 70% (compared to a prior art yield of 32%) and also increases the purity of the target sodium salt.
