It relates to a preparation process of 2'-(benzyloxy)-3'-nitro-1,1'-biphenyl-3- carboxylic acid or a salt thereof comprising reacting 2-(benzyloxy)-1-bromo- 3-nitrobenzene with a either 3-carboxyphenylboronic acid or a salt thereof or a (C 1 -C 4 )-alkyl ester thereof in the presence of Pd(OAc) 2 , tricydohexylphosphine, a base, an appropriate solvent, and at an appropriate temperature; if appropriate, submitting the compound thus obtained to a hydrolysis reaction; and isolating the compound thus obtained in form of a salt of compound of formula (VI) or in form of the free acid by adding an acid. It also comprises the further preparation to eltrombopag or its salts from the new intermediate thus obtained by subsequent reduction of the nitro group and deprotection of the phenol, conversion of the amine intermediate obtained in a diazonium derivative, and either (1) subsequent reaction with ethyl acetoacetate and with (3,4-dimethylphenyl)hydrazine or a salt thereof, occurring the pyrazole ring formation by intermolecular cyclization, or (2) introduction of the pyrazole ring by reaction with 1-(3,4-dimethylphenyl)-3-methyl-3-pyrazolin-5-one.
摘要:
A method for producing a therapeutic agent [10] and the agent [10] thus produced. This therapeutic agent [10], referred to as D-boramine [10], has the following chemical formula: [(CH 3 ) 3 NCH 2 CHOHCH 2 CO 2 H] 2 [O 2 CCHOHCHOHCO 2 ] and has the following empirical formula: C 18 H 36 N 2 O 12 . The D-boramine [10] is produced by allowing a reaction between approximately 500mg of L-carnitine and approximately 2.5 mg of pyridoxal 5 phosphate in the presence of approximately 10 mg of fumaric acid. The reaction creates the D-boramine [10] molecule as the reaction product. The D-boramine [10] molecule has an orthorhombic crystalline structure and has been shown to be useful as a therapeutic agent in treating a variety of human cancers, ailments and diseases.
