A novel synthesis of 3-substituted indazole derivatives
Welch,Hanau,Whalen
, p. 937 - 939 (1992)
The dianion prepared from 3-bromo-1H-indazole and alkyllithium bases reacts with a variety of electrophiles to give the corresponding 3-monosubstituted 1H-indazole derivatives in moderate yields. This procedure is more general and shorter than earlier methods.
