The methylation of 2naphthol to prepare 2methoxynaphthalene. Two different procedures are demonstrated in this video, one from Vogel with dimethyl sulfate and the other with methyl iodide (iodomethane) using a general (and somewhat lazy) Williamson ether synthesis.
2Methoxynaphthalene is used as a pleasantsmelling perfume ingredient and a chemical building block.
