Procedure

To a mixture of 23.1 g. of naphthyl magnesium bromide and 250 ml. of diethyl ether, 7 g. of cyclobutanone are slowly added. After the addition, the mixture is refluxed for one hour, cooled, acidified with aqueous hydrochloric acid and filtered. The product is isolated by methylene chloride extraction to furnish 2-(1'-hydroxycyclobutyl)-naphthalene. The product is hydrogenated in 200 ml. of ethanol with a molar equivalent of hydrogen in the presence of 50 g. of Raney nickel; the reaction mixture is filtered after the hydrogenation and evaporated to furnish 2-cyclobutylnaphthalene.
