An efficient route to 3-aminoindazoles and 3-amino-7-azaindazoles
摘要:
A non-acidic procedure for the preparation of 3-aminoindazoles and 3-amino-7-azaindazoles from 2-fluoroaryl carboxylic acids is reported. The synthesis starts from readily available starting materials and uses mild and practical reaction conditions in a three-step overall procedure. Products were isolated for a number of examples, but yields varied significantly depending on electronic nature of the substituents. (c) 2008 Elsevier Ltd. All rights reserved.
