反応手順
4-Methyl-1-methoxynaphthalene (4) (145 g) was mixed with pyridine hydrochloride (250 g) and the mixture was heated at 200° C. for 3 hours. The mixture was cooled, treated with dilute hydrochloric acid, and extracted with ether. The ether extract was dried (MgSO4), filtered and the solvent removed, leaving a black oil which was extracted with petroleum b.p. 60°-80° C. (4×100 cm3). 4-Methyl-1-naphthol (5) was obtained as near colourless oily crystals which darken on storage.
