标 题 :Solid phase synthesis of salts of organic acid
发明人：VAN DYCK STEFAAN
权利人:KEMIN IND INC
摘要:A process for the solid-phase synthesis of salts of organic acids in a granular, free-flowing, and dust-free form particularly suited for use as animal feed additives. A liquid organic acid is applied to an inert, absorbent carrier. A solid base is then added during stirring. The acid is slowly released from the carrier preventing the fast reactions that lead to the formation of clumps. The exothermic reaction releases heat which assists in reducing the moisture content of the product.

摘要:This invention relates to a method for the preparation of a compound of formula I: I a key intermediate in the synthesis of a series of Angiotensin II receptor antagonists. The invention also relates to a selective reagent for conducting the Hofmann rearrangement, particularly in the formation of a pyridinoimidazolone, which is a percursor to the formation of an imidazopyfidine of formula I. This invention also relates to a method for the preparation of imidazolutidine, a key intermediate in the synthesis of 3-(2'-(N-benzoyl)sulfonamidobiphen-4-yl)-methyl-5,7 -dimethyl-2-ethyl-3H-imidazo[4,5-b]pyridine, using pyridinoimidazolone, an unreactive urea.
