Novel sulfonyl chlorides of quinolines and isoquinolines have successfully been prepared. This enabled the preparation of the corresponding sulfonamides via reaction with an amine using the "resin-capture and release" methodology.

A Novel Class of Orally Active Non-Peptide Bradykinin B<sub>2</sub> Receptor Antagonists. 3. Discovering Bioisosteres of the Imidazo[1,2-<i>a</i>]pyridine Moiety
Recently we reported on overcoming the species difference of our first orallyactivenon-peptide bradykinin (BK) B2 receptor antagonists, incorporating an 8-[[3-(N-acylglycyl-N-methylamino)-2, 6-dichlorobenzyl]oxy]-3-halo-2-methylimidazo[1,2-a]pyridine skeleton, leading to identification of the first clinical candidate 4a (FR167344). With this potent new lead compound in hand, we then investigated
