  Indazoles: Regioselective Protection and Subsequent Amine Coupling Reactions

  摘要：

  Indazoles are unselectively protected under strongly basic conditions to give a mixture at N-1 and N-2. Under mildly acidic conditions, regioselective protection at N-2 takes place. Thermodynamic conditions lead to regioselective protection at N-1. This trend applies to various substituted indazoles. Protected 5-bromoindazoles participate in Buchwald reactions with a range of amines to generate novel derivative.
