Title:
NEW BICYCLIC DERIVATIVES OF PYRIDINES, THEIR PREPARATION, OBTAINED NEW INTERMEDIATES, THEIR USE AS DRUG AND PHARMACEUTICAL COMPOSITION CONTAINING THEM
Document Type and Number:
Japanese Patent JP3535534
Kind Code:
B2
Abstract:

PURPOSE: To obtain new bicyclic derivs. of pyridines useful as antagonists to angiotensin II receptors.
CONSTITUTION: The bicyclic derivs. of pyridines are compds. of formula I [where one of A and B is N and the other is C; the dotted line makes the pyridinyl ring satd. or unsatd.; R is a 1-6C alkyl, 3-7C cycloalkyl or the like; R1 to R4 are each -(CH2)m1-S(O)m2-X-R14 (m1 is 0-4; m2 is 0-2; and X-R14 is amino, a 1-6C alkyl, phenyl or the like), H, a halogen, OH, 1-6C alkyl, aryl or the like; and Y is -Y1-B-Y2 (Y1 is a 5- or 6-membered monocyclic aryl, an 8- to 10-membered synthetic ring; B is a single bond, -CO-, -NH-CO- or the like; and Y2 is Y1, H, cyano or the like)], e.g. 2-butyl-3-[(2'-1H-tetrazol-5-yl)(1,1'- biphenyl)-4-yl-methyl]pyrazolo[1,5-a]pyridine-4-carboxylic acid. The compds. of the formula I are obtd. by allowing compds. of formula II [where R'1 to R'4 are (protected) R1 to R4] to react with compds. of formula III [where R' and Y' are (protected) R and Y].
