On February 1, 2007, Brooks, Carl; Cleary, Pamela A.; Goodman, Krista B.; Peace, Simon; Philp, Joanne; Sehon, Clark A.; Smethurst, Christian; Watson, Stephen Paul published a patent.Electric Literature of 13544-06-4 The title of the patent was Preparation of azolylmethylbenzenesulfonamides as CCR2 chemokine receptor antagonists.. And the patent contained the following:
Title compounds [I; R1 = (substituted) aryl, thienyl, benzothienyl, imidazolyl, pyridyl, isoquinolinyl, piperonyl, benxoxathiadiazolyl, benzodiazolyl; m = 1-3; R2 = halo, cyano, OCF3, CF3; R3 = (substituted) heteroaryl, heterocycloalkyl], were prepared as CCR2 chemokine receptor antagonists (no data). Thus, [5-chloro-2-(1H-1,2,3-triazol-1-ylmethyl)phenyl]amine (preparation given) in pyridine was treated with 4-dimethylaminopyridine and 3,4-dichlorobenzoyl chloride followed by heating of the mixture at 90掳 for 4 h to give 3,4-dichloro-N-[5-chloro-2-(1H-1,2,3-triazol-1-ylmethyl)phenyl]benzenesulfonamide. The experimental process involved the reaction of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile(cas: 13544-06-4).Electric Literature of 13544-06-4
