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 1 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.
