Treatment of unprotected 5-amino-4-methylpyrimidine (2) with n-BuLi gave dianion 3. Direct condensation of the dianion with various carboxylic acid derivatives furnished a range of 2-substituted-4,6-diazaindoles in good yields in one step without the need for protecting groups or oxidation-state adjustment.
