The present invention relates to novel urea derivatives and, more particularly, to novel urea derivatives with histone deacetylase (HDAC) inhibitory activity, isomers thereof, pharmaceutically acceptable salts thereof, their use for the preparation of a medicaments comprising the same, a pharmaceutical composition comprising the same, a treatment method using the composition, and a method for preparing novel urea derivatives. The novel urea derivatives as selective histone deacetylase (HDAC) inhibitors are effective for the treatment of histone deacetylase-mediated diseases such as malignant tumors, inflammatory diseases, rheumatoid arthritis, neurodegeneration, etc.
A procedure has been developed for the regioselective, high yielding synthesis of 2H-indazoles.

offer exciting possibilities in organic synthesis but remains largely unknown. Herein, we report the use of allyl electrophiles in nickel-catalyzed conjunctive cross-coupling with a non-conjugated alkene and dimethylzinc. The transformation is enabled by weakly coordinating, monodentate aza-heterocycle directing groups that are useful building blocks in synthesis, including saccharin, pyridones, pyrazoles

Disclosed is a method of making a 1-alkylindazole comprising reacting a 1-acylindazole with a first reducing agent, and contacting the resulting mixture with an acid anhydride or acyl halide, and with pyridine or a 4-dialkylaminopyridine or a combination of pyridine and a 4-dialkylaminopyridine, to form a hemiaminal ester and reacting the hemiaminal ester with a second reducing agent to form a 1-alkylindazole. Also disclosed are intermediates for the synthesis of 1-alkylindazoles.

Methods of making indazoles are described. The methods involved reacting an aromatic aldehyde with a nitrogen source to form a nitroso aromatic aldehyde. The nitroso aromatic aldehyde is reacted with a reducing agent to form an indazole which ultimately can be used to form desired indazoles which are preferably pharmaceutically active products. The process of the present invention further permits the formation of enantiomerically enriched or pure indazoles such as aminoalkyl indazoles.
