Abstract
A facile and efficient method for one-pot N-alkylation of nucleobases and azole derivatives from alcohols using triphenylphosphine in carbon tetrachloride is described. In this method, treatment of alcohols with a mixture of triphenylphosphine, carbon tetrachloride, nucleobase or azole derivatives and potassium carbonate in the presence of catalytic amounts of tetra-n-butylammonium iodide (TBAI) in refluxing N,N-dimethylformamide, furnishes the corresponding N-alkyl derivatives in good yields. This methodology is highly efficient for various structurally diverse primary alcohols and also useful for N-alkylation of other N-heterocycles containing an acidic N―H bond.
