摘要： The present invention provides novel methods for preparing 5-(trifluoromethoxy)-1H-3-indazolecarboxylic acid (3), which is a useful precursor for the preparation of bicyclic-5-trifluoromethoxy-1H-indazole-3-carboxylic acid amides of Formula (1). Compounds of Formula (1) are active as agonists and partial agonists of the nicotinic α-7 receptor and are being studied for their use in the treatment of disease conditions associated with defective or malfunctioning nicotinic acetylcholine receptors, especially of the brain, such as for the treatment of Alzheimer's disease and schizophrenia, as well as other psychiatric and neurological disorders. The present methods are useful for preparing compound (3) on scale up levels.

摘要： The present invention provides novel methods for stabilizing lithiated halogen-substituted aromatic compounds. In particular, the method is useful for the preparation of 2-methoxy-5,6-difluorobenzaldehyde, an important intermediate for the preparation of [4-amino-2-(1-methanesulfonylpiperidin-4-ylamino)pyrimidin-5-yl](2,3-difluoro-6methoxyphenyl)methanone, a potent and selective inhibitor of CDK4/Cyclin D1, CDK2/Cyclin E and CDK1/Cyclin B. The method is also useful for stabilizing other lithiated halogen-substituted aromatic compounds and is particularly useful for scale up reactions where the exothermic nature of the reaction can lead to reaction runway.
