Abstract: PURPOSE: Provided are β-aminoalcohol derivative containing pyridine, its pharmaceutically acceptable salt and its manufacturing method. The β-aminoalcohol derivative has a hypotensive effect and reduces weight, and is thus used as a therapeutic gent in hyperglycemia related diseases or obesity. CONSTITUTION: β-aminoalcohol derivative containing pyridine is represented by the formula(I), wherein A is halogen atom or haloalkyl substituted or unsubstituted phenyl, thiophene, phenyloxymethyl, naphthyloxymethyl, or biphenyloxymethyl group; R is hydrogen or C1-4 alkyl group; Y is methylene or oxygen; and G is at least one substituent selected from the group consisting of hydrogen, halogen atom, C1-3 alkyl, alkoxy, amino, cyano, phenyl substituted urea, phenyl or C1-3 alkyl substituted carboxamide, carboxylester, alkoxy carbonyl methyloxy, alkoxycarbonylalkyl group, alkoxycarbonylacryl and tetrazol group. It is manufactured by condensation reaction with a compound of the formula(II) and a compound of the formula(III) and hydrogenation with organic metal catalyst.
