been used to alkylate alcohols in the presence of sodium hydride. This is a simple and efficient method for the synthesis of ethers from complex alcohols and an alternative to the usual O-alkylation methods. This method was especially important for the preparation of monofluoromethyl ethers of a wide range of alcohols. Some alkylatedderivatives of the precursors of some bioactive compounds were also
